based on polyethylene wax<br />
Licowax PE 520 is a colorless, odourless,<br />
hard, partially branched-chain<br />
polyethylene wax <strong>of</strong> low density.<br />
Because <strong>of</strong> its molecular structure<br />
Licowax PE 520 has a pronounced<br />
matting effect on paint. It is readily<br />
dispersible in hot solvent <strong>and</strong> produces<br />
fine dispersions with good resistance<br />
to settling.<br />
8<br />
Licowax PED 521 <strong>and</strong> Licowax PED<br />
522 are partially branched-chain<br />
polar polyethylene waxes.<br />
The Ceridust grades are micropowders<br />
produced by a special process.<br />
Ceridust 3620 is a linear, hard polyethylene<br />
wax. Ceridust 9615 A is a<br />
modified linear polyethylene wax.<br />
Ceridust 6721 is a new br<strong>and</strong> <strong>of</strong> a<br />

(PTFE). They are noted <strong>for</strong><br />
excellent slip.<br />
Ceridust 3920 F <strong>and</strong> TP Ceridust 3921 F<br />
are PTFE modified polyethylene waxes<br />
with a very low average particle size<br />
diameter <strong>of</strong> approx. 6.0 µm. There<strong>for</strong>e<br />
<strong>the</strong>y are especially suitable <strong>for</strong> improving<br />
<strong>the</strong> surface lubricity <strong>and</strong> slip<br />
properties in thin film applications.<br />
The Ceridust grades can be finely<br />
dispersed in paints <strong>of</strong> different systems<br />
simply <strong>and</strong> with little mechanical<br />
energy.
Waxes <strong>and</strong> wax micropowders<br />
based on o<strong>the</strong>r raw materials<br />
Licowax C micropowder is a hard<br />
highmelting-point amide wax that can<br />
be easily ground <strong>and</strong> dispersed owing<br />
to its brittleness.<br />
Ceridust 3910 is an especially finegrain<br />
micropowder based on amide<br />
wax; it can be processed with ease<br />
due to its small particle size. Both<br />
wax micropowders exhibit slip which<br />
is advantageous in de<strong>for</strong>mation <strong>and</strong><br />
s<strong>and</strong>ing work.<br />
The Ceridust grades 9202 F <strong>and</strong><br />
9205 F are a low molecular weight<br />
PTFE characterized by antisticking<br />
properties <strong>and</strong> a related surface<br />
effect.<br />

The mode <strong>of</strong> action <strong>of</strong> <strong>the</strong> Licowax<br />
<strong>and</strong> Ceridust grades summarized in<br />
section “Function <strong>of</strong> Waxes” opens<br />
up many uses <strong>for</strong> <strong>the</strong>se products in<br />
<strong>the</strong> paint <strong>and</strong> <strong>coating</strong>s sector.<br />
14<br />
Matting<br />
The so-called matt effect <strong>of</strong> paints <strong>and</strong><br />
o<strong>the</strong>r surface <strong>coating</strong>s is produced by<br />
a large number <strong>of</strong> microscopically<br />
small particles that reflect <strong>the</strong> incident<br />
light diffusely. The particle size is <strong>of</strong><br />
crucial importance. Particles visible to<br />
<strong>the</strong> eye with a diameter <strong>of</strong> >20 µm do<br />
not produce a good matt effect.<br />
The ideal particle size is about 10 µm.<br />
Particles with a diameter
Enhancing antiblocking behaviour<br />
The micronized waxes Ceridust 9615 A,<br />
Ceridust 6721, Ceridust 9610 F <strong>and</strong><br />
Ceridust 9630 F have proved particularly<br />
successful in producing an antiblocking<br />
effect in solvent-containing<br />
paints. Ceridust 9615 A exhibits <strong>the</strong><br />
smallest <strong>and</strong> Ceridust 9630 F <strong>the</strong><br />
greatest effect.<br />
Ceridust 3920 F <strong>and</strong> TP Ceridust 3921 F<br />
are primarily suitable <strong>for</strong> can <strong>and</strong> coil<br />
<strong>coating</strong>s where low COF is required.<br />
A special grade <strong>of</strong> PTFE will impart<br />
superior slip <strong>and</strong> anti-blocking<br />
properties.<br />
Improving s<strong>and</strong>ability<br />
In lacquers based on polyurethane,<br />
in acid-curing lacquers <strong>and</strong> furniture<br />
lacquers based on nitrocellulose, <strong>the</strong><br />
addition <strong>of</strong> Licowax C micropowder<br />
has proved successful in improving <strong>the</strong><br />
s<strong>and</strong>ability <strong>of</strong> primers. So that <strong>the</strong> wax<br />
can function optimally, it should first<br />
be dispersed in a solvent suited to <strong>the</strong><br />
recipe with <strong>the</strong> help <strong>of</strong> a bead mill, <strong>for</strong><br />
example (see page 24).<br />
Influencing <strong>the</strong> rheological properties<br />
Licowax PED 521 <strong>and</strong> Licowax PED 522<br />
have proved highly successful <strong>for</strong><br />
preventing sagging <strong>and</strong> running <strong>of</strong><br />
alkyd resin paints (page 25).<br />
Preventing pigment settling<br />
Even small quantities <strong>of</strong> Ceridust<br />
9615 A – 0.5 % to 1.5 % relative to <strong>the</strong><br />
binder – delay <strong>the</strong> settlement <strong>of</strong> pigments<br />
<strong>and</strong> fillers to <strong>for</strong>m a hard sediment.<br />
Sediments do <strong>for</strong>m after some<br />
time but are easily redispersed. An<br />
even more effective way <strong>of</strong> preventing<br />
settling is to use Licowax PE 520 as<br />
a 10 % dispersion. Preparation <strong>of</strong> <strong>the</strong><br />
dispersion is described under<br />
“Preparation <strong>of</strong> a wax dispersion”<br />
on page 18.<br />
In order to improve <strong>the</strong> settling behaviour<br />
<strong>of</strong> pearl-gloss pigments,<br />
Licowax 371 FP can be used <strong>and</strong> is<br />
added as a 6 % dispersion to <strong>the</strong> paint<br />
system. Preparation <strong>of</strong> this dispersion<br />
is described on page 15 in section<br />
“Licowax 371 FP”.<br />
Making paints water-repellent<br />
Ceridust 9615 A is suitable <strong>for</strong> making<br />
protective wood finishes <strong>and</strong> protective<br />
wood stains water-repellent. 2 %<br />
to 6 % <strong>of</strong> <strong>the</strong> product incorporated<br />
in <strong>the</strong> finished paint give <strong>the</strong> film good<br />
water repellency at <strong>the</strong> initial drying<br />
stage; in addition excellent film<br />
smoothness is achieved (page 25).<br />
Preventing metal markings<br />
No metal markings <strong>of</strong> any kind may<br />
occur when metal tools are used on<br />
coated steel strip (coil-coated metal).<br />
This is achieved by adding Ceridust<br />
9610 F, Ceridust 9630 F, Ceridust<br />
3920 F or TP Ceridust 3921 F.<br />
These Ceridust grades have proved<br />
successful with highly matt coil<br />
<strong>coating</strong>s. Fur<strong>the</strong>rmore, <strong>the</strong> painted<br />
surface should be as insensitive as<br />
possible, so that in everyday domestic<br />
use contact with metallic objects<br />
does not leave any marks (table 1).<br />
Superior surface slip<br />
Ceridust 9325 F <strong>and</strong> TP Ceridust 9322 F<br />
are modified PE wax/PTFE blends that<br />
are primarily suitable <strong>for</strong> giving additional<br />
surface slip. The very low mean<br />
particle size diameter <strong>of</strong> only 6 µm<br />
makes TP Ceridust 9322 F extremely<br />
valuable <strong>for</strong> any thin film application.<br />

General in<strong>for</strong>mation on<br />
<strong>the</strong> processing <strong>of</strong> waxes<br />
The waxes described here are insoluble<br />
at room temperature in <strong>the</strong> common<br />
paint solvents. They dissolve only at<br />
elevated temperatures in aromatic<br />
<strong>and</strong> a number <strong>of</strong> aliphatic solvents,<br />
mainly nonpolar hydrocarbons. When<br />
<strong>the</strong> wax/solvent mixture cools, <strong>the</strong><br />
wax precipitates with varying degrees<br />
<strong>of</strong> crystallinity <strong>and</strong> remains finely<br />
dispersed in <strong>the</strong> solvent. By altering<br />
<strong>the</strong> type <strong>and</strong> quantity <strong>of</strong> <strong>the</strong> components<br />
<strong>and</strong> <strong>the</strong> dispersion method, it is<br />
possible to vary <strong>the</strong> dispersing operation<br />
considerably so as to achieve<br />
differences in <strong>the</strong> structure <strong>of</strong> <strong>the</strong><br />
particles <strong>and</strong> <strong>the</strong> degree <strong>of</strong> dispersion<br />
<strong>and</strong> thus in <strong>the</strong> consistency <strong>of</strong> <strong>the</strong><br />
dispersion.<br />
Similar fine dispersions can be produced<br />
using Ceridust without hot precipitation.<br />
These micronized powders <strong>of</strong>fer <strong>the</strong><br />
following advantages:<br />
> No heating <strong>of</strong> wax <strong>and</strong><br />
solvent required.<br />
> No solvent vapours arise.<br />
> The risk <strong>of</strong> fire is reduced<br />
to a minimum.<br />
> Necessary dispersing machines are<br />
in operation <strong>for</strong> a short time only,<br />
thus saving time <strong>and</strong> energy.<br />
> Processing is environmentally safe.<br />
18<br />
Additions <strong>of</strong> 1% to 5 % wax, relative to<br />
<strong>the</strong> ready-to-use paint, have proved<br />
successful in practice. Higher additions<br />
are likely to cause impairment <strong>of</strong><br />
<strong>the</strong> paint film in <strong>the</strong> <strong>for</strong>m <strong>of</strong> chalking,<br />
cratering, pinholing <strong>and</strong> deterioration<br />
<strong>of</strong> re<strong>coating</strong> properties <strong>and</strong> intercoat<br />
adhesion.<br />
Licowax PE 520<br />
The Licowax PE 520, which is supplied<br />
in <strong>the</strong> <strong>for</strong>m <strong>of</strong> granules, fine grain <strong>and</strong><br />
powder, cannot be incorporated directly<br />
into paint systems. It is necessary first<br />
to produce fine wax particles by dissolving<br />
<strong>and</strong> precipitating <strong>the</strong> product.<br />
The following methods are suitable:<br />
> Hot precipitation<br />
Heat 2 parts by weight Licowax PE<br />
520 with 18 parts by weight solvent,<br />
mainly composed <strong>of</strong> aromatics, to<br />
about 100 °C; <strong>the</strong> resultant solution<br />
must be clear. Stir this solution into<br />
80 parts by weight cold paint. With<br />
this procedure <strong>the</strong> wax is precipitated<br />
in <strong>the</strong> paint in a very finely<br />
dispersed <strong>for</strong>m <strong>and</strong> has hardly any<br />
tendency to settle.<br />
> Preparation <strong>of</strong> a wax dispersion<br />
An approx. 10 % dispersion in xylene<br />
can be prepared by <strong>the</strong> following<br />
simple method: Heat 10 parts by<br />
weight Licowax PE 520 <strong>and</strong> 30 parts<br />
by weight xylene to about 100 °C,<br />
<strong>the</strong>reby dissolving <strong>the</strong> wax. After<br />
cooling <strong>the</strong> solution to about 96 °C<br />
stir into 60 parts by weight cold<br />
xylene. 1% to 5 % wax in <strong>the</strong> paint<br />
is recommended depending on <strong>the</strong><br />
matt effect required.
Licowax PED 521, Licowax PED 522<br />
Dissolve 20 to 30 parts by weight<br />
Licowax PED 521 or Licowax PED 522<br />
at about 90 °C in 80 to 70 parts by<br />
weight xylene or white spirit. Cool <strong>the</strong><br />
hot solution to room temperature with<br />
slight stirring <strong>and</strong> incorporate in <strong>the</strong><br />
paint (page 25).<br />
Licowax 371 FP<br />
Heat 6 parts by weight Licowax 371 FP<br />
<strong>and</strong> 30 parts by weight xylene to<br />
100 °C <strong>and</strong> cool while stirring to 75 °C.<br />
After reaching this temperature,<br />
<strong>the</strong> solution is diluted with 64 parts by<br />
weight butyl acetate 98/100 % while<br />
stirring <strong>and</strong> cooled to room temperature.<br />
The wax content in <strong>the</strong> finished<br />
paint should be about 1-2 %.<br />
Ceridust 9615 A, Ceridust 6721<br />
The micronized powders can be stirred<br />
directly into <strong>the</strong> paint. A minimum<br />
mixing time <strong>of</strong> 15 minutes is advisable<br />
to ensure satisfactory wetting <strong>of</strong> <strong>the</strong><br />
individual wax particles (page 22).<br />
However, it is expedient first to prepare<br />
a stock paste. It is sufficient to admix<br />
20-30 % Ceridust micropowder with a<br />
suitable solvent <strong>and</strong> to stir <strong>the</strong> batch<br />
<strong>for</strong> about 15 minutes. Very homogeneous<br />
dispersions with good stability to<br />
settling are obtained by <strong>the</strong> additional<br />
use <strong>of</strong> a small amount <strong>of</strong> binder. This<br />

Ceridust 3910<br />
Ceridust 3910 has very fine particles.<br />
It can be stirred slowly direct into <strong>the</strong><br />
paint system (normally 1 % to 2 %).<br />
The stirring time should be at least<br />
10 minutes. Subsequent thickening <strong>of</strong><br />
such dispersions may occur. In this<br />
case <strong>the</strong> viscosity can be lowered by<br />
stirring again thoroughly.<br />
Licowax C micropowder<br />
Very fine dispersions with a maximum<br />
solids content <strong>of</strong> 15 % <strong>and</strong> an average<br />
particle size <strong>of</strong> about 3.5 µm can be<br />
produced by dispersing Licowax C<br />
micropowder in <strong>the</strong> appropriate<br />
solvent in a bead, s<strong>and</strong> or ball mill.<br />

Ceridust 3920 F, TP Ceridust 3921 F,<br />
Ceridust 9325 F, TP Ceridust 9322 F<br />
Like all Ceridust grades, <strong>the</strong>se products<br />
can be stirred directly into <strong>the</strong> paint<br />
system. An addition <strong>of</strong> 0.8 to 1.5 % by<br />
weight is sufficient in view <strong>of</strong> <strong>the</strong> high<br />
efficacy <strong>of</strong> <strong>the</strong> different PTFE contents<br />
<strong>of</strong> <strong>the</strong> Ceridust grades 9610 F, 9630 F,<br />
3920 F, 3921 F, 9325 F <strong>and</strong> 9322 F.<br />
The mixing time should be at least 15<br />
minutes to achieve adequate wetting<br />
<strong>of</strong> <strong>the</strong> individual wax particles.<br />
Ceridust 9630 F in particular, with its<br />
higher PTFE content, should be mixed<br />
in <strong>the</strong> <strong>for</strong>m <strong>of</strong> a masterbatch into <strong>the</strong><br />
binder <strong>and</strong> <strong>the</strong>n added to <strong>the</strong> paint. In<br />
a highly mobile paint Ceridust 9630 F<br />
tends to settle because <strong>of</strong> its higher<br />
density.<br />
Ceridust 9202 F, Ceridust 9205 F<br />
These pure PTFE grades can be processed<br />
similarly to Ceridust 9630 F.<br />
Quantity added: 0.3 to 0.8 % by weight.
Ceridust <strong>and</strong> waterbased<br />
<strong>Coatings</strong><br />
Ceridust 3715, Ceridust 2440,<br />
Ceridust 3719 <strong>and</strong> Ceridust 5551<br />
These grades are micronized powders<br />
with improved wetting properties<br />
specially developed <strong>for</strong> water-thinnable<br />
paints <strong>and</strong> aqueous systems. The<br />
following methods are suitable <strong>for</strong><br />
incorporating <strong>the</strong>m in paints <strong>and</strong><br />
surface <strong>coating</strong>s:<br />
Stir direct into <strong>the</strong> paint system;<br />
<strong>the</strong> mixing time should be at least<br />
15 minutes.<br />
In case that co-solvent is used as part<br />
<strong>of</strong> <strong>the</strong> water-based <strong>coating</strong> <strong>for</strong>mulation<br />
<strong>the</strong> dispersion <strong>of</strong> <strong>the</strong> micronized wax<br />
can be improved by preparing a highly<br />
concentrated wax dispersion which<br />
will <strong>the</strong>n be subsequently added to<br />
<strong>the</strong> <strong>for</strong>mulation. This procedure ensures<br />
an adequate wetting <strong>of</strong> <strong>the</strong> wax<br />
particles <strong>and</strong> avoids high shear <strong>for</strong>ces<br />
<strong>for</strong> <strong>the</strong> binder system as <strong>the</strong>se systems<br />
can be shear sensitive. Trials have<br />
proven that solvents like butylglycol,<br />
butyldiglycol, <strong>and</strong> DPM are ideal<br />
<strong>for</strong> <strong>the</strong> dispersing <strong>of</strong> <strong>the</strong> mentioned<br />
micronized waxes. Depending on<br />
<strong>the</strong> solvent <strong>and</strong> type <strong>of</strong> wax concentrations<br />
<strong>of</strong> approx. 40 % are possible<br />
without <strong>the</strong> use <strong>of</strong> any additves.<br />
In <strong>the</strong> case <strong>of</strong> pigmented systems,<br />
Ceridust is processed toge<strong>the</strong>r with<br />
<strong>the</strong> pigments <strong>and</strong> fillers. A stirring<br />
time <strong>of</strong> 15 minutes is generally sufficient<br />
<strong>for</strong> adequate wetting <strong>of</strong> <strong>the</strong> wax<br />
particles.<br />
If <strong>the</strong> dry film thickness <strong>of</strong> <strong>the</strong> <strong>coating</strong>,<br />
especially in can <strong>coating</strong> <strong>and</strong> metal<br />
decoration, is to be < 12 µm, it is advisable<br />
to disperse <strong>the</strong> wax in <strong>the</strong><br />
appropriate binder/solvent mixture by<br />
means <strong>of</strong> a bead mill or similar machine.<br />
20 % to 30 % wax preparations<br />
can be produced.<br />
If wetting is inadequate, it should be<br />
borne in mind that Ceridust 3715, 2440<br />
or 3719 tend to cream in aqueous<br />
systems <strong>and</strong> not to settle as in solventcontaining<br />
systems.<br />
Since many water-thinnable binders<br />
are alkaline or have to be adjusted<br />
with amines to a pH <strong>of</strong> 8 to 9, foaming<br />
<strong>of</strong> varying degrees <strong>of</strong> severity may<br />
occur when Ceridust is stirred in. If<br />
<strong>the</strong> <strong>coating</strong> contains too much foam,<br />
film defects occur when it is applied.<br />
In this case a silicone-free defoamer<br />
has to be added. The quantities to be<br />
added must be determined in preliminary<br />
trials.<br />

UV reactive waxes<br />
TP Ceridust 5091, TP Ceridust 5851 R<br />
TP Ceridust 5091 <strong>and</strong> TP Ceridust<br />
5851 R feature an entirely new wax<br />
chemistry by making Montan ester<br />
waxes UV reactive. Thus this newly<br />
designed micronized waxes are<br />
enable to polymerize in any given<br />
UV cured <strong>coating</strong> system. As <strong>the</strong><br />
wax is linked to <strong>the</strong> polymer matrix<br />
<strong>the</strong>re is little to no migration to <strong>the</strong><br />
surface <strong>of</strong> <strong>the</strong> <strong>coating</strong>. The benefits<br />
<strong>of</strong> this new technology are long<br />
lasting improvement <strong>of</strong> scratch <strong>and</strong><br />
mar resistance, slip <strong>and</strong> abrasion<br />
resistance <strong>and</strong> inreased water <strong>and</strong><br />
chemical resistance.<br />
TP Ceridust 5851 R can improve <strong>the</strong><br />
already excellent matting properties<br />
<strong>of</strong> TP Ceridust 5091 due to a unique<br />
blend <strong>of</strong> UV reactive wax <strong>and</strong> a<br />
specialty matting ingredient.<br />

Matting<br />
Nitrocellulose lacquers<br />
Nitrocellulose lacquers, whose main<br />
component is cellulose nitrate, are<br />
still used on a wide scale <strong>for</strong> furniture<br />
lacquers. The matting agent used in<br />
<strong>the</strong>se lacquers is almost exclusively<br />
wax. The most important products <strong>for</strong><br />
this purpose are Licowax PE 520,<br />
Ceridust 9615 A <strong>and</strong> Ceridust 6721.<br />
When low-viscosity curtain-<strong>coating</strong><br />
paints are manufactured, it is advisable<br />
to incorporate Licowax PE 520 by hot<br />
precipitation (page 18).<br />
Ceridust 9615 A or Ceridust 6721 are<br />
better suited to paints applied by<br />
spray or brush. It tends to settle out<br />
slightly when left to st<strong>and</strong> <strong>for</strong> some<br />
time but can be readily redispersed<br />
by stirring. To prevent settling out as<br />
far as possible it is advisable to use<br />

Frequently <strong>the</strong> tendency <strong>of</strong> Ceridust<br />
9615 A or Ceridust 6721 to settle is due<br />
to inadequate wetting <strong>of</strong> <strong>the</strong> individual<br />
wax particles. In this case we recommend<br />
that a paint /wax concentrate<br />
should be prepared. The following<br />
procedure is recommended: incorporate<br />
25 to 30 parts by weight Ceridust<br />
in 75 to 70 parts by weight <strong>of</strong> <strong>the</strong> paint<br />
to be matted <strong>and</strong> continue to stir until<br />

Can <strong>coating</strong>s<br />
Improved slip behaviour <strong>and</strong> enhanced<br />
scratch resistance in can <strong>coating</strong>s<br />
can be achieved by using PTEE containing<br />
waxes such as Ceridust 9610 F,<br />
Ceridust 9630 F or Ceridust 3920 F.<br />
These micronized waxes can be<br />
processed directly into <strong>the</strong> lacquer.<br />

The components shall be mixed <strong>and</strong><br />
well homogenized in <strong>the</strong> above described<br />
order by using a dissolver.<br />
For this application, a wax dosage <strong>of</strong><br />
0.5-1 % has proved to be advantageous.<br />
Coil <strong>coating</strong>s<br />
A positive effect on slip behaviour <strong>and</strong><br />
scratch resistance can be achieved<br />
by using PTFE-containing waxes in<br />
coil <strong>coating</strong>s.<br />
Especially recommended <strong>for</strong> this<br />
application are <strong>the</strong> following Ceridust<br />
grades:<br />
> Ceridust 9610 F<br />
> Ceridust 9630 F<br />
> Ceridust 3920 F<br />
> TP Ceridust 3921 F<br />
> Ceridust 9325 F<br />
> TP Ceridust 9322 F<br />
Excellent results can be achieved by<br />
using 0.5 to 1.0 % wax.<br />

Safety data<br />
Toxicological properties<br />
The polyethylene <strong>and</strong> amide waxes<br />
described in this leaflet as well as<br />
waxes based on crude montan wax<br />
have no properties that are harmful to<br />
health on <strong>the</strong> basis <strong>of</strong> experience to<br />
date. The acute oral toxicity (LD50 ) <strong>of</strong><br />
<strong>the</strong>se waxes is > 2000 mg/kg in <strong>the</strong><br />
rat or mouse.<br />
When Ceridust 9610 F, Ceridust 9630 F,<br />
Ceridust 3920 F, TP Ceridust 3921 F,<br />
Ceridust 9325 F, TP Ceridust 9322 F,<br />
Ceridust 9202 F <strong>and</strong> Ceridust 9205 F are<br />
h<strong>and</strong>led, <strong>the</strong> usual safety precautions<br />
<strong>for</strong> fluorocarbon-containing products<br />
must be observed. Contamination<br />
<strong>of</strong> clo<strong>the</strong>s <strong>and</strong> tobacco products must<br />
be avoided at all costs. Hazardous<br />
decomposition products occur<br />
above 300 °C.<br />
28<br />
Ecological properties<br />
The waxes described are virtually<br />
insoluble in water. Hence <strong>the</strong>y are<br />
attacked only very slowly by microorganisms<br />
in water <strong>and</strong> cause no<br />
significant biological oxygen dem<strong>and</strong>.<br />
They are eliminated from <strong>the</strong> effluent<br />
as ballast toge<strong>the</strong>r with <strong>the</strong> sludge.<br />
The COD eliminability under <strong>the</strong><br />
conditions <strong>of</strong> sewage treatment is<br />
good (> 95 %). The waxes should<br />
be taken to an authorized site <strong>for</strong><br />
disposal.
