Transformer Oil Leak<br />
<strong>Repair</strong><br />
One Minute Epoxy / Flexane® 80 Putty<br />
2/14/96<br />
B. C. Hydro<br />
Utility Power Distribution<br />
Problem:<br />
Inspection of 4Kv <strong>and</strong> 12Kv transformers revealed excessive leaking oil from both the bushing, flange<br />
<strong>and</strong> fastener areas. The leaking was so severe that either side of the transformer tank was covered with<br />
a thick film of oil. De-energizing <strong>and</strong> installing new gaskets would require a 6 week shutdown.<br />
Shutdown <strong>and</strong> repair cost was estimated to be $70K.<br />
Solution:<br />
Leaking or repair areas of the transformer were s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. One<br />
Minute Epoxy was applied to plug all active leaks. Following confirmation that all leaks had stopped,<br />
repair areas were chemically cleaned using Cleaner Blend 300. Both FL10 <strong>and</strong> FL20 Primers were<br />
applied <strong>and</strong> each allowed to cure or dry for 15 minutes. Using both primers will improve Flexane 80<br />
Putty adhesion from 25 pli to 50 pli. Flexane 80 Putty was applied to a thickness of 1/8”, extending<br />
beyond the One Minute Epoxy by 1-2 inches. GoJo h<strong>and</strong> cleaner was used to smooth <strong>and</strong> sculpt<br />
Flexane 80 Putty following gel point. <strong>Devcon</strong>’s repair cost was $4.5K with only a 3 day shutdown..

Canada Cement Lafarge<br />
Cement Manufacturing<br />
Problem:<br />
These pneumatic conveying pipes would receive extreme abrasive wear from processing fine cement<br />
particulate. The previous method of repair was to fabricate new pipes. Fabricating new pipes was an<br />
expensive repair procedure <strong>and</strong> caused flange <strong>and</strong> fastener misalignment when re-assembling due to<br />
heat distortion.<br />
Solution:<br />
<strong>Repair</strong> surfaces were s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Surface area was then chemically<br />
cleaned using Cleaner Blend 300. Ceramic <strong>Repair</strong> Putty was applied to worn areas deeper than 1/8”.<br />
Following a partial cure of Ceramic <strong>Repair</strong> Putty, (4 hours), Brushable Ceramic was applied to a<br />
thickness of 25 mils. Following a partial cure of Brushable Ceramic, (4 hours), a second coat of<br />
Brushable Ceramic was applied a 25 mils. . Brushable Ceramic encapsulated the repair areas <strong>and</strong><br />
provided a long lasting, abrasion resistant, protective surface coating.

Flexane® 94 Liquid<br />
2/11/97<br />
Hyundai<br />
Construction<br />
Problem:<br />
Undersea road support structures required moving onto a submergible barge for placement into the sea.<br />
To provide a smooth <strong>and</strong> level surface on the barge deck, ITW Chockfast was used. Due to the enormous<br />
weight of the support structures, <strong>and</strong> the flexing of the barge from rolling seas, cracking occurred.<br />
Surface cracking <strong>and</strong> hollow, uneven expansion joints caused extreme difficulty when rolling the support<br />
structures onto the barge.<br />
Solution:<br />
Because of extremely high compressive strength <strong>and</strong> excellent flexibility, Flexane 94 Liquid was used to<br />
fill expansion joints <strong>and</strong> repair cracked areas on the barge deck. Crack <strong>and</strong> expansion joint areas were<br />
roughened <strong>and</strong> then chemically cleaned using Cleaner Blend 300. Expansion joints were filled or stuffed<br />
with a polypropylene backer. This prevented Flexane 94 Liquid from migrating deep into the concrete.<br />
FL20 Primer was applied <strong>and</strong> allowed to cure or dry for 15 minutes. Flexane 94 Liquid was poured into<br />
the expansion joints <strong>and</strong> cracks. Flexane 94 Liquid provided a smooth, flexible, (350% elongation), level<br />
surface allowing the structure to be moved easily <strong>and</strong> safely.

Hyundai<br />
Construction<br />
Problem:<br />
Undersea road support structures required moving onto a submergible barge for placement into the sea.<br />
The structures enormous weight needed to be supported <strong>and</strong> moved onto the submergible barge.<br />
Common rubber could not be used as wheels due to low compressive strength. Common rubber would<br />
lose it’s cylindrical shape <strong>and</strong> cause the structure to seize when moved.<br />
Solution:<br />
Because of extremely high compressive strength, Flexane 94 liquid was molded <strong>and</strong> manufactured into<br />
wheels <strong>and</strong> as compressive shock absorbing pads. Flexane 94 Liquid easily supported the weight <strong>and</strong><br />
allowed the structure to be moved easily <strong>and</strong> safely. When manufacturing parts, <strong>Devcon</strong> Release Agent<br />
must be used for easy part removal or separation from the mold.

Coal Dust Valve <strong>Repair</strong><br />
Titanium Putty / Brushable Ceramic<br />
2/15/94<br />
Canada Cement Lafarge<br />
Cement Manufacturing<br />
Problem:<br />
Fine coal dust particulate would cause extreme wear to the seal areas on this valve. Because the wear<br />
was 1/8”, the seal was compromised allowing coal dust to seep through the valve when in the closed<br />
position.<br />
Solution:<br />
The repair area was roughened using a grinder <strong>and</strong> wire wheel attachment. <strong>Repair</strong> area was then<br />
chemically cleaned using Cleaner Blend 300. A generous coating of release agent was applied to the<br />
butterfly valve. Titanium Putty was mixed <strong>and</strong> applied to the valve body, rebuilding the missing metal.<br />
The Titanium Putty was smoothed, sculpted <strong>and</strong> feathered using acetone. The butterfly valve with<br />
release agent applied, was closed <strong>and</strong> used as a forming mold. Following a 4 hour cure, the valve was<br />
opened. Three coats of Brushable Ceramic were applied totaling 25 mils. Brushable Ceramic<br />
encapsulated the repair areas <strong>and</strong> provided a long lasting, abrasion resistant protective surface coating.

Petrochemical Liquid Natural Gas Manufacturing<br />
Problem:<br />
Vessel <strong>and</strong> exchanger channels, valves <strong>and</strong> piping would receive extreme corrosive damage from the<br />
process of manufacturing liquid natural gas. Each manufacturing train would be completely refitted<br />
every 3 years. Equipment <strong>and</strong> machinery replacement would not only be cost prohibitive, but would<br />
cause realignment <strong>and</strong> fitting problems when reassembled.<br />
Solution:<br />
All repair <strong>and</strong> coating surfaces were s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Complete repair<br />
areas were chemically cleaned using Cleaner Blend 300. All corroded areas over 1/8” deep, were<br />
filled using Ceramic <strong>Repair</strong> Putty. Following a partial cure of Ceramic <strong>Repair</strong> Putty, (4 hours),<br />
Brushable Ceramic was applied to a thickness of 30 mils. Brushable Ceramic encapsulated the repair<br />
areas <strong>and</strong> provided a long lasting, low co-efficient to friction, chemical resistant protective coating.<br />
Following a partial cure of the first coat of Brushable Ceramic, (4 hours), a second coat of Brushable<br />
Ceramic was applied, again to a thickness of 30 mils. <strong>Devcon</strong>’s repair procedure is estimated to save<br />
hundreds of thous<strong>and</strong> of dollars annually.

Flexane® 80 Liquid Fast Cure<br />
3/21/96<br />
Ontario Hydro<br />
Utility Power Distribution<br />
Problem:<br />
These utility power poles would receive extreme damage from nesting woodpeckers. The woodpecker<br />
would peck a nest as deep as five feet from the entrance hole. This damage would leave only a wooden<br />
shell offering little resistance to wind, ice, <strong>and</strong> snow. The damaged pole could no longer support the<br />
weight of the cables <strong>and</strong> required replacement. Power pole replacement cost was estimated to be $4K<br />
Solution:<br />
An injection port was first drilled into the power pole above the repair area. Wooden dowels were place<br />
into the void. Placing wooden dowels reduced the volume of Flexane 80 Liquid Fast Cure required to fill<br />
the void. Flexane 80 Liquid Fast Cure was injected through the injection port. Flexane 80 Liquid flowed<br />
evenly throughout the void rebuilding the missing wood. <strong>Devcon</strong>’s repair cost was $300.

Deep Pour Grout<br />
March 1998<br />
Baltimore Gas & Electric<br />
Power Plant<br />
Problem:<br />
A centrifugal water pump pad was badly eroded <strong>and</strong> the pump plate became very loose. Severe vibration<br />
occurred <strong>and</strong> the anchor bolts became loose in the concrete. Over a period of time “chunks” of concrete<br />
broke away causing the plate to become very sloppy.<br />
Solution:<br />
The loose concrete was removed using a surface grinder. All loose particles were blown away with high<br />
pressure air. The surface was then cleaned with a degreaser to remove all oil <strong>and</strong> grease. Fir strips were<br />
used to “dam” the edges of the pump pad. The pump base plate was balanced on the concrete surface.<br />
Then Deep Pour Grout was poured onto the pad <strong>and</strong> allowed to “self level”. After 16 hours the plate was<br />
secure in the epoxy <strong>and</strong> ready for the pump to be re-connected.

Rebuilding Motor Pad<br />
Deep Pour Grout <strong>and</strong> 1-Minute® Epoxy<br />
March 1998<br />
Coastal Refinery<br />
Petrochemical Plant<br />
Problem:<br />
Concrete motor pad becomes broken up after intense vibration of pump motor vibrating over time.<br />
Broken <strong>and</strong> spalled concrete needed to be removed <strong>and</strong> the area cleaned of all loose fragments. A<br />
wooden form will be placed in the area to be rebuilt, spanning the spalled area of the motor pad. Then a<br />
new set of anchor bolts placed to secure the motor.<br />
Solution:<br />
After the loose concrete was removed from the surface, a pine form was anchored in place using 1-<br />
Minute Epoxy to secure to concrete an d seal area from any grout traveling under the form. Then Deep<br />
Pour Grout was mixed <strong>and</strong> poured into one side of the hole. The material moves freely displacing air as<br />
the grout fills all crevices. The material self levels nicely for a smooth finish. A anchor bolt is placed<br />
into the grout approx. 20 minutes after the pour. After 24 hours the motor is mounted back onto the pad.

Sprayable Ceramic Ceramic <strong>Repair</strong> Putty.<br />
February 98<br />
B G & E Power<br />
Power Plant<br />
Problem:<br />
Rebuilt intake water circulating pump that has been worn through caviation over the years. The veloute<br />
areas have seen quite a bit of erosion of metal. The pump is so large that the plant wants to spray a coating<br />
onto the surface for easy of application for the mechanics<br />
Solution:<br />
First the pump area is s<strong>and</strong>blasted to a SSPC 10 finish. Then degreased using our Cleaner Blend 300 which<br />
leaves no residue. This leaves a good 3-5 mil profile for application of our materials. Ceramic <strong>Repair</strong><br />
Putty is applied to the large spalled areas of metal over 1/8” deep. This helps to fill in these worn areas.<br />
Next the Sprayable Ceramic is coated at a 20-30 mil coating in one pass over the entire pump. A wet film<br />
gauge is used to gauge the thickness. After 6-8 hours a second coat of the Sprayable Ceramic is coated<br />
onto the pump for a finish of 40-60 mils. This makes for a strong chemical <strong>and</strong> abrasion resistant coating.

Flotation Cell <strong>Repair</strong><br />
Brushable Ceramic <strong>and</strong> Ultra Quartz<br />
January 1998<br />
Nor<strong>and</strong>a Mine (Brunswick Mine Division)<br />
Mining<br />
Problem:<br />
Floatation Cells see tremendous corrosion by the fact that the ore is abrading the sides of the tanks<br />
constantly! Any coating you apply must have great abrasion resistance. Galvanic corrosion occurs at the<br />
steel surfaces rather quickly once abrasion starts! The floor of the Floatation Cell sees the sediment of the<br />
ore which is very abrasive, <strong>and</strong> needs repairing regularly.<br />
Solution:<br />
The Flotation Cells are first blasted to a SSPC -SP5 white metal blast to remove all corrosion from the<br />
surface. Any large holes are filled in with Titanium Putty. Next Brushable Ceramic is rolled onto the area<br />
using a 1/4” nap roller. Two coats are recommended . Each at 14-18 mils thick. Between coats the<br />
coating is checked for a “holidays” with a Leak Detector Kit. The finish coating provides a tough durable<br />
abrasion resistant finish against the aggregate. The floor is troweled with 3/8” of Ultra Quartz for final<br />
protection. The Ultra Quartz is troweled up the side wall approximately 4 inches for a seamless finish.

Problem:<br />
The mating area between the ball mill shell <strong>and</strong> the head would receive extreme wear from an abrasive<br />
slurry washout. The wear was so severe that the metal was worn in excess of 1/8” deep.<br />
Solution:<br />
The complete repair area was roughened using a grinder <strong>and</strong> wire wheel attachment. Following<br />
roughening the complete area was chemically cleaned using Cleaner Blend 300. Eight holes were drill<br />
equally spaced around the diameter of the mating area. The mating area void was then sealed from the<br />
outside using PorRok. Sealing the mating area void eliminated any migration or flowing of Plastic Steel<br />
Liquid. Plastic Steel Liquid was then mixed using a drill <strong>and</strong> mixing tool. Following mixing, Plastic Steel<br />
Liquid was poured into the mating area void using a funnel. The funnel improved flow rate. Pouring<br />
started at the lowest point injection holes. A steel plate was welded over the holes when the Plastic steel<br />
would reach the hole. This process continued until the void was completely filled. Replacement of the<br />
Mill Head was estimated at $160K. <strong>Devcon</strong> cost of repair was only $10K!

Problem:<br />
Dry coal “fines “ would collect on the trough of the screw conveyer <strong>and</strong> on the screw flyghts. The<br />
constant abrasion will cause cavataion in the trough <strong>and</strong> prevent proper conveying of the coal. Thusly<br />
the trough needed to be rebuilt back to its close tolerance to the flyghts.<br />
Solution:<br />
First the trough was blasted to a SSPC-SP5 near white blast <strong>and</strong> solvent wiped. Then Ceramic <strong>Repair</strong><br />
was applied to the worn gouges <strong>and</strong> holes in the trough to “build up” the large voids. After the material<br />
was cured for at least (4 hours) Brushable Ceramic was applied to a thickness of 30 mils in two coats of<br />
15 mils each. Next the “screw” itself was coated with two coats of Brushable Ceramic (30 mils total) in<br />

Floor Patch - Ultra Quartz - EC7000 AR<br />
6-12-99<br />
Alcoa Aluminum<br />
Processing<br />
Problem:<br />
In the processing of aluminum in making cans, high concentrations of acids are used. These acids are<br />
contained in large tanks <strong>and</strong> used in groups in containment areas. These containment areas see “spills”<br />
which cause the concrete to be “eaten away” because of chemical attack. This application shows up to<br />
12” deep“trenches” into the concrete which harbors the acid in these pools, attacking the concrete even<br />
more.<br />
Solution:<br />
First, the floor was rinsed multiple times with water to “neutralize” the acid condition of the floor. After,<br />
dried Floor Patch was used to fill the large trenches, (12” deep), in the concrete around the tank areas.<br />
Before the Floor Patch cures, our chemical resistant Ultra Quartz was used to apply a final ¼” topcoat<br />
onto the entire surface for ultimate chemical resistance to the acid. All drains <strong>and</strong> sloped areas were<br />
shaped at this time for good drainage. Then a coating of Epoxy Coat 7000AR (12-15 mils) was applied<br />
over the entire containment area for acid resistance. This tank area is now protected for any spills that<br />
may occur.

Brushable Ceramic<br />
3-15-99<br />
Syncrude, Ft. McMurray<br />
Mining<br />
Problem:<br />
In mines, water feed pumps “wear” because of abrasive particles flowing through the volutes at<br />
tremendous speeds, causing wear <strong>and</strong> abrasion inside the volute <strong>and</strong> impeller areas. Pump casings are<br />
very expensive <strong>and</strong> instead of “replacing” the volutes, metal-filled epoxies are used to rebuild loose metal.<br />
These polymers act as better “wear resistant” finishes on the surface. In this pump, the volute areas had<br />
wear up to 1” deep, which had to be filled before a protective coating could be applied.<br />
Solution:<br />
The volute of the pump casing was s<strong>and</strong>blasted to an SSPC-SP5 white metal finish. After blasting, the<br />
pump was cleaned with our Cleaner Blend 300 to remove all residual abrasive shot from the surface.<br />
Then a primer coat of Brushable Ceramic (12-15 mils) was coated on all areas. Immediately after coating<br />
with Brushable Ceramic, the large voids (over 1” deep), were filled with Wear Guard High Load. The<br />
Brushable Ceramic acts as a primer helping the beaded epoxy adhere better to the surface. Next, Ceramic<br />
<strong>Repair</strong> was used to fill all other voids (under ½” deep). Finally, a topcoat of Brushable Ceramic (12-<br />
15mils) was used for a smooth, final chemical resistant finish.

Chicago Road Service<br />
Cement Manufacturing<br />
Problem:<br />
The fins or paddles within this portable cement mixer would receive extreme abrasive wear from<br />
continually agitating cement. Previous method of repair was to protect fins or paddles by covering with<br />
U.H.M.W. This repair procedure was expensive <strong>and</strong> time consuming.<br />
Solution:<br />
<strong>Repair</strong> surfaces were s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Exp<strong>and</strong>able metal was tack welded in<br />
a raised position 25 mils above the substrate. Tack welding exp<strong>and</strong>able metal above the substrate<br />
improved the mechanical bonding properties of Wear Guard Fine Load. Weld slag was removed using a<br />
grinder <strong>and</strong> wire wheel attachment. All surfaces were then chemically cleaned using Cleaner Blend 300.<br />
Wear Guard Fine Load was applied using a trowel to a thickness of 1/2”. Wear Guard Fine Load was<br />
pressed through the exp<strong>and</strong>able metal forcing complete contact onto the substrate surface. Wear Guard<br />
Fine Load was smoothed, contoured <strong>and</strong> feathered using acetone as a thinning agent following gel point.

Problem:<br />
Over several years of continual traffic, these expansion joints became deteriorated. As a result of failed<br />
expansion joints, spider cracking began. The uneven floor surface caused problems such as difficulty<br />
moving wheeled equipment, <strong>and</strong> forklift load shifting.<br />
Solution:<br />
Loose, deteriorated concrete was mechanically removed. Remaining concrete was roughened to provide a<br />
profile. All surface areas were then chemically cleaned using Cleaner Blend 300. FL20 Primer was<br />
applied into the expansion joints <strong>and</strong> cracks <strong>and</strong> allowed to cure or dry for 15 minutes. A polypropylene<br />
backer was stuffed 3/4” into the expansion joints <strong>and</strong> cracks. The polypropylene backer will prevent deep<br />
migration of Fast Cure Liquid, <strong>and</strong> reduce the volume required. Fast Cure Rubber <strong>Repair</strong> Liquid was<br />
injected into the damaged or repair areas using <strong>Devcon</strong>’s Auto Mix Application System. This product is<br />
self- leveling <strong>and</strong> provided a smooth, flexible, (450% elongation), expansion joint seal. Fast Cure Rubber<br />

Problem:<br />
Weld porosity’s caused seeping oil leaks from this substation transformer. The past repair procedure was<br />
to drain the oil from the tank <strong>and</strong> re-weld. This repair process was expensive <strong>and</strong> caused long term power<br />
outages.<br />
Solution:<br />
<strong>Repair</strong> or leak areas were roughened using a grinder. One Minute Epoxy was applied using the Mark 5<br />
Auto Mix System to plug all active leaks. Following confirmation that all oil leaks had been stopped,<br />
repair areas were then chemically cleaned using Cleaner Blend 300. Fasmetal was then applied directly<br />
over the One Minute Epoxy to a thickness of 1/4, extending beyond the One Minute Epoxy by 3mm.<br />
Following Fasmetal’s 1 hour cure, repair areas were primed using both FL10 <strong>and</strong> FL20 Primers. Each<br />
primer was allowed to cure or dry for 15 minutes. Using both primers on metal substrates will improve<br />
adhesion from 25 pli to 50 pli. Two primer system is always recommended in wet or outdoor operating<br />
conditions. Flexane 80 Putty was applied over the Fasmetal to a thickness of 1/4” extending beyond by 3<br />
inches.. Flexane 80 Putty encapsulated the repair area as a flexible, (350% elongation), vibration <strong>and</strong><br />

Solution:<br />
<strong>Repair</strong> areas were hydroblasted to remove loose concrete <strong>and</strong> clean contaminates. Cracks <strong>and</strong> joints were<br />
filled using a polypropylene backer. This prevented the Flexane 80 Liquid from migrating deep into the<br />
concrete. Crack <strong>and</strong> joint surfaces were then primed with FL20 Primer. FL20 Primer was allowed to cure<br />

Machine Shop<br />
Problem:<br />
Loading dock areas in plants see continuous “wear <strong>and</strong> tear” from forklifts running back <strong>and</strong> forth into<br />
trucks carrying pallets of material that abrade across the floor. Once these areas become “smooth”, they<br />
are dangerously slippery when water gets on the surface. The plant wanted to skid-proof the shipping<br />
area in front of the loading bays, which would hold up to heavy forklift traffic, yet coat the floor with an<br />
epoxy that could be cleaned up easily everyday <strong>and</strong> look good. A real dilemma!<br />
Solution:<br />
The area was degreased with a good cleaner to remove all oil <strong>and</strong> dirt. The floor was etched with<br />
<strong>Devcon</strong>’s B-4 Etcher in dock area. After the floor was cleaned <strong>and</strong> dried, a coating of Epoxy Concrete<br />
Sealer was rolled onto the surface. Silicone carbide grit was then broad-casted onto the floor. After<br />
material cured, backer rod was installed in the expansion/control joints, then a top coat of Epoxy<br />
Concrete Sealer (with grey colorant) was rolled over first coat, removing backer rod after coating the<br />
area. The finished floor has an epoxy topcoat with silicone carbide underneath for skid proofing that can<br />
be easily cleaned.

Problem:<br />
This Urethane wear ring would receive extreme abrasive wear from processing a slurry of gold ore <strong>and</strong><br />
water. The past repair method was to return to the manufacturer for re-surfacing. This repair procedure<br />
was costly <strong>and</strong> caused extensive downtime. Current repair method cost was $700 each unit.<br />
Solution:<br />
A wood model was built using a new ring as the mold. The metal ring was s<strong>and</strong>blasted to a SSPC-SP5<br />
white metal finish. <strong>Repair</strong> surface was then chemically cleaned using Cleaner Blend 300. Both FL10 <strong>and</strong><br />
FL20 Primers were applied <strong>and</strong> each allowed to cure or dry for 15 minutes. Using both primers will<br />
improve adhesion from 25 pli to 50 pli. A generous coating of <strong>Devcon</strong>’s Release Agent was applied to<br />
the wood model. Release Agent must be applied for easy removal or separation of molded parts. Flexane<br />
80 Liquid was injected into the mold forming a new urethane surface, bonding to the metal ring.<br />
Following full cure of Flexane 80 Liquid, (24 hours), the manufactured part was removed from the mold.<br />
<strong>Devcon</strong>’s repair cost was $25 each unit.

Problem:<br />
This stainless steel water circulation pump impeller received extreme cavitation from processing high<br />
velocity cooling water. The pump could not be removed from it’s operating position. This required the<br />
repair be completed in wet conditions <strong>and</strong> in an overhead position.<br />
Solution:<br />
The damaged areas on the impeller blades were roughened by h<strong>and</strong> using a wire brush. Complete repair<br />
areas were then pressure washed with distilled water. Surface area was then chemically cleaned using<br />
Cleaner Blend 300. Underwater <strong>Repair</strong> Putty was applied to damaged areas, covered with pliable plastic<br />
paper, <strong>and</strong> compressed or formed. The plastic paper protected the Underwater <strong>Repair</strong> Putty from being<br />
eroded by the continual flow of water while curing. Following a 2 hour cure of Underwater <strong>Repair</strong> Putty,<br />

Circle C Equipment<br />
Agriculture<br />
Problem:<br />
Farmers use rubber rolls to flatten hay in order to speed up the drying process of the hay. Occasionally<br />
rocks will tear apart sections of these rolls reducing their effectiveness to dry the hay. Resurfacing the roll<br />
with new rubber has an estimated cost of $1,500, besides enormous “downtime” as the farmer must send<br />
the roll to the shop to be resurfaced. This “do-it-yourself” system would allow the farmer to repair the roll<br />
the same day.<br />
Solution:<br />
<strong>Devcon</strong>’s Flexane Belt <strong>Repair</strong> Kit is a complete “do-it-yourself” system that a farmer can repair the rolls<br />
themselves. All repair areas were s<strong>and</strong>blasted or abraded using a wire brush. Next, Cleaner Blend 300<br />
was applied to the metal roll to thoroughly clean all contaminants. FL-10 is used to prime the metal roll<br />
while FL-20 is used to prime areas that will come in contact with the existing rubber surface. Flexane 80<br />
Putty is then applied to the roll core building up to the existing roll. Grooves are then made in the Flexane<br />
80 prior to setting up to match the existing rubber roll. Farmers now repair their rubber rolls in 24 hours!<br />
<strong>Devcon</strong>’s repair cost per roll is $100. While sending them out for repair averages $1,500. A major cost<br />
savings for the farmer.

months life expectancy <strong>and</strong> thy wanted more! The flights of the auger wear over time from abrasion of<br />
the material against the flight walls. In this application , the customer “hard-faced” welded one auger <strong>and</strong><br />
coated a similar auger with <strong>Devcon</strong>’s Wear Guard Fine Load 300<br />
Both augers went into service for 13 month to determine what method worked the best! As can be seen<br />
from the photos, the auger with <strong>Devcon</strong> shows virtually no wear! Measurements taken indicate how<br />
well the <strong>Devcon</strong> product has performed over hard-face welding.<br />
Solution:<br />
Starting at the drive end the numbers below show the wear of the four flights on the auger,. All numbers<br />
are in millimeters with nominal flight thickness being 5/8” or 16mm. These numbers show the wear<br />
over the past thirteen months<br />
Hard-face welded flights: 14mm 13mm 9mm 10mm<br />
<strong>Devcon</strong> coated flights: 22mm 20mm 21mm (22mm is slightly less than 7/8”)<br />
<strong>Devcon</strong>’s Wear Guard High Load 300 has proven itself to be superior in extending the life of the auger.<br />
After determining the remaining wear of the flights the <strong>Devcon</strong> coated auger would still have<br />
approximately 12 months of additional service before wearing out. Wear Guard has doubled the life of<br />
the auger!<br />
Besides the extended wearing qualities of Wear Guard Fine Load the cost to coat the augers were $1044<br />
[with 45 minutes labor to coat] compared to hard-facing which was $694/each [with 5-7 hours to coat].<br />
The total savings to coat all 12 augurs were $25,000! All new augers will be coated before allowed in<br />
service with <strong>Devcon</strong>’s Wear Guard Fine Load 300.

Ball Mill <strong>Repair</strong><br />
<strong>Devcon</strong>® Irathane® 155<br />
01/15/02<br />
South American Copper/Gold mine<br />
Mining<br />
Problem:<br />
The customer had purchased a used milling line. The ball mill in the system was very worn on all<br />
surfaces, including the covers. This was due to defects in the internal coating, which allowed leakage of<br />
the pulp between liner <strong>and</strong> shell. The customer needed to restore worn dimensions to original condition,<br />
<strong>and</strong> prevent future problems. <strong>and</strong> used Wear Guard Fine Load on all worn areas. The whole surface was<br />
then coated with Irathane 155 as protection against possible future liner failure.<br />
Solution:<br />
Complete surface was blasted to white metal (SSPC-SP5). Surface was then cleaned with Cleaner Blend<br />
300. When the surface was dry, eroded areas were repaired with Wear Guard Fine Load. Within 4 hours,<br />
the substrate was primed with SA-200 applied with airless spray equipment. This was allowed to dry for 3<br />
hours, when Irathane 155 was applied, using 42:1 ratio airless equipment. Two coats of 155 were applied,<br />
achieving a total DFT of 2.5 mm. <strong>Repair</strong>s were made <strong>and</strong> future damage prevented, using two <strong>Devcon</strong><br />
systems.

Ball Mill Trunnion<br />
<strong>Repair</strong> <strong>and</strong> Lining<br />
Combo Wear, Flexane® 80 Putty<br />
July 2002<br />
South American Copper Mine<br />
Mining<br />
Problem:<br />
The ball mill suffered extreme wear in the trunnion liner feed area, <strong>and</strong> in the area where it joins the mill.<br />
This wear threatened to endanger the system, since if the trunnion liner should be perforated, process<br />
water <strong>and</strong> pulp would enter the chamber between the liner <strong>and</strong> the trunnion, leading to critical wear <strong>and</strong><br />
equipment shutdown.<br />
Solution:<br />
The trunnion liner <strong>and</strong> joint area with the mill was grit blasted <strong>and</strong> cleaned with Cleaner Blend 300.<br />
<strong>Devcon</strong> Combo Wear FC beaded epoxy was mixed <strong>and</strong> applied 6-10 mm thick with a trowel. This was<br />
allowed to cure for 40 minutes, after which Flexane 80 Putty was applied in a 6mm coat. This was<br />
allowed to cure for a few hours <strong>and</strong> the mill was put back in operation.

Conveyor Belt Diverter<br />
Lining<br />
Tile Adhesive, Ferro Ceramic Tiles<br />
March 2002<br />
South American Copper/Gold mine<br />
Mining<br />
Problem:<br />
The customer installed a system in the milling line in which one conveyor belt feeds 3 different chutes. A<br />
diverter distributes the material, including rocks up to 2” diameter, to the desired chute.<br />
Solution:<br />
Given the potential for abrasion of the diverter, Ferro br<strong>and</strong> ceramic tiles (100x150 mm x ½” thick) were<br />
applied for protection. The substrate (metal plate) was blasted to white metal <strong>and</strong> cleaned with Cleaner<br />
Blend 300. <strong>Devcon</strong> Tile Adhesive was spread onto the diverter, in a 1/8” thick coat. The tiles were then<br />
placed onto the adhesive, which is very resistant to abrasion <strong>and</strong> impact.
