Field Application Reports Products: Application Date: Customer: Industry: Location 33 Floor Repair Acid Environment Floor Patch - Ultra Quartz - EC7000 AR 6-12-99 Alcoa Aluminum Processing Problem: In the processing of aluminum in making cans, high concentrations of acids are used. These acids are contained in large tanks and used in groups in containment areas. These containment areas see “spills” which cause the concrete to be “eaten away” because of chemical attack. This application shows up to 12” deep“trenches” into the concrete which harbors the acid in these pools, attacking the concrete even more. Solution: First, the floor was rinsed multiple times with water to “neutralize” the acid condition of the floor. After, dried Floor Patch was used to fill the large trenches, (12” deep), in the concrete around the tank areas. Before the Floor Patch cures, our chemical resistant Ultra Quartz was used to apply a final ¼” topcoat onto the entire surface for ultimate chemical resistance to the acid. All drains and sloped areas were shaped at this time for good drainage. Then a coating of Epoxy Coat 7000AR (12-15 mils) was applied over the entire containment area for acid resistance. This tank area is now protected for any spills that may occur.
Field Application Reports Products: Application Date: Customer: Industry: Location 34 Conveyor Belt Repair Flexane® 80 Putty 6/8/94 Ash Grove Cement Cement Manufacturing Problem: Conveyor belts would receive extreme impact abrasive wear from processing aggregate. Past repair process was to vulcanize. Vulcanizing was an expensive repair process usually causing long downtime periods. Solution: Complete repair area was roughened using a grinder and wire wheel attachment. Following roughening, surface area was chemically cleaned using Cleaner Blend 300. FL20 Primer was applied and allowed to cure or dry for 15 minutes. Flexane 80 Putty, was mixed and let set up for 30 minutes. Flexane 80 was smoothed and contoured by covering and compressing with a pliable polypropylene sheet. Following functional cure of Flexane 80 Putty, 12 hours, the polypropylene sheet was easily removed.
