Overview of pigment properties 22 - 23<br />

For <strong>powder</strong> <strong>coating</strong>s, BASF offers pigments tested for <strong>coating</strong>s<br />

applications (L grades) as well as plastics application (K grades).<br />

Experience has shown that when it comes to finely divided<br />

organic pigments, the respective K grade is often <strong>more</strong> readily<br />

dispersible and has higher color strength than the L grade of<br />

the same chemical constitution.<br />

The K grades have been especially designed with respect to the<br />

size, distribution and shape of their particles for processing<br />

conditions in the plastics industry (processing in extruders and<br />

calenders) and that these advantages also extend to the manufacture<br />

of <strong>powder</strong> <strong>coating</strong>s. From the L range we particularly<br />

recommend the HD grades (hiding and dispersibility).<br />

Inorganic pigments<br />

Hybrid pigments<br />

Most inorganic pigments are stable in the usual commercial<br />

<strong>powder</strong> <strong>coating</strong> resins even at elevated temperatures and are<br />

largely resistant to chemical and physical effects. They often differ<br />

from organic pigments in having a much higher hiding power<br />

and high weather resistance. The relatively low specific surface<br />

and high specific gravity of inorganic pigments have a positive<br />

influence on the rheological properties of <strong>powder</strong> <strong>coating</strong>s.<br />

BASF’s hybrid pigments are supplied under the Paliotan ® trademark,<br />

consisting of bismuth vanadate and a high-quality organic<br />

pigment. They provide an ideal combination of the advantages<br />

of inorganic (high hiding power) and organic (chroma, high color<br />

strength) pigments, while at the same time offering high cost<br />

efficiency. The most economic Paliotan ® types are based on<br />

different inorganic components.<br />

Our pigment selection takes into account the clear trend in the<br />

<strong>powder</strong> <strong>coating</strong>s industry towards raw materials that are not<br />

subject to labeling requirements and we supply only lead- and<br />

cadmium-free grades.


Organic pigments<br />

Only a range of organic color pigments can provide the maximum<br />

scope of coloristic possibilities. However, not every<br />

coloristically interesting pigment is suitable for application in<br />

<strong>powder</strong> <strong>coating</strong>s. The colorants must first satisfy a series of<br />

basic technical/physical requirements. These include heat<br />

resistance, dispersibility and good shade reproducibility.<br />

Special attention was paid to these criteria in drawing up the<br />

following pigment selection, which can <strong>make</strong> it much easier<br />

for the user to put together his final assortment. Since in practice<br />

there are a great variety of applications, each with its own<br />

requirements, we cannot consider every application possibility<br />

here. <strong>We</strong> therefore recommend appropriate preliminary tests<br />

under the user’s own specific production conditions.<br />

Examples of desirable properties:<br />

• resistance to amines and amides<br />

• hiding power<br />

• dispersibility<br />

• color strength<br />

• chromaticity<br />

• minimum plate-out<br />

• heat resistance<br />

• minimum thermochromism<br />

• suitability for over<strong>coating</strong><br />

• fastness to weathering<br />

• cost efficiency<br />

Sicopal ® / Sicotan ®<br />

Inorganic pigments<br />

Sicopal ® pigments<br />

These bismuth vanadate pigments are brilliant, greenish yellow<br />

colorants whose applications include the manufacture of leadfree,<br />

high-quality <strong>powder</strong> <strong>coating</strong>s. Special features of the<br />

Sicopal ® Yellow pigments are high purity of shade and excellent<br />

hiding power. Their resistance to weathering is outstanding both<br />

in full shades and in reductions with titanium dioxide. Sicopal ®<br />

Yellow pigments have proved to be successful substitution<br />

products for lead pigments. Shades such as RAL 1021 and RAL<br />

1028, which are difficult to achieve without using lead-based<br />

pigments, are easily obtained with Sicopal ® Yellow pigments.<br />

The standard pigment is Sicopal ® Yellow L 1100. Sicopal ® Yellow<br />

L 1120 has a slightly redder with improved chroma. It is <strong>more</strong><br />

heat-resistant in Primid ®1 crosslinked <strong>powder</strong> <strong>coating</strong>s and its<br />

hiding power and weather fastness are also outstanding.<br />

To match reddish shades we recommend the much redder<br />

alternative Sicopal ® Yellow L 1600, whose hue often allows the<br />

amount of organic shading pigments in the formulation to be<br />

reduced. The color of bismuth vanadate pigments is stable at<br />

normal baking temperatures (180 °C - 210 °C). However,<br />

severe overbaking (e.g., 60 min at 210 °C) may result in coloristic<br />

changes towards a duller, darker shade and in the formation<br />

of various surface structures (e.g., craters), depending on the<br />

resin/curing agent system used. Changes in film hardness have<br />

also been observed. Where especially good heat stability is<br />

required, we recommend suitable preliminary tests under the<br />

appropriate conditions.<br />

Sicopal ® Yellow grades are supplied exclusively as low-dusting<br />

fine granules. They are not subject to labeling requirements.<br />

Recommended for <strong>powder</strong> <strong>coating</strong> application are:<br />

Sicopal ® Yellow L 1100 P.Y. 184<br />

Sicopal ® Yellow L 1120 P.Y. 184<br />

Sicopal ® Yellow L 1600 P.Y. 184


Sicotan ® pigments<br />

The Sicotan ® Yellow grades are complex inorganic chromatic<br />

pigments. Of coloristic significance are the lemon-yellow nickel<br />

titanates (e.g., Sicotan ® Yellow L 1010) and the ocher-colored<br />

chromium titanates, for example Sicotan ® Yellow L 2110.<br />

Sicotan ® Yellow pigments are ideal for use in <strong>powder</strong> <strong>coating</strong>s.<br />

High heat stability, high hiding power and maximum fastness to<br />

weathering <strong>make</strong> them ideal for combination with organic<br />

yellow, orange and red pigments, yielding a broad spectrum of<br />

shades that meet all the requirements with respect to brilliance<br />

and high hiding power. It is often possible to use less organic<br />

pigments in formulations with Sicotan ® Yellow pigments than<br />

with titanium dioxide. This reduces the PVC (pigment volume<br />

concentration), which has a positive effect on the flow properties<br />

and also has economic benefits.<br />

Sicotan ® Yellow grades are also supplied as low-dusting, freeflowing<br />

fine granules. Such fine granules offer advantages in<br />

large-scale processing (weighing, automatic metering) and at the<br />

same time have a smaller physiological impact on personnel.<br />

Paliotan ®<br />

Hybrid pigments<br />

Paliotan ® pigments<br />

With Paliotan ® Yellow pigments, shades that were previously<br />

difficult to formulate, such as RAL 1003, 1007, 1021 und 1028,<br />

can be produced lead-free without technical difficulties. They<br />

meet requirements for hiding power, vivid color and fastness to<br />

weathering to a high degree. They can therefore be used in both<br />

industrial polyester and architectural <strong>powder</strong> <strong>coating</strong>s. Where<br />

cost efficiency is a <strong>more</strong> important consideration than fastness<br />

to weathering in formulating the <strong>coating</strong>s, choice should focus<br />

on Paliotan ® Yellow L 1135, Paliotan ® Orange L 2935 and<br />

Paliotan ® Red L 3735.


Recommended grades for <strong>powder</strong> <strong>coating</strong>s with<br />

good fastness to weathering:<br />

Grades for <strong>powder</strong> <strong>coating</strong>s whose fastness to<br />

weathering is not of primary concern:<br />

Paliotan ® Yellow L 1145<br />

Paliotan ® Yellow L 1645<br />

Paliotan ® Yellow L 1945<br />

Paliotan ® Yellow L 1135<br />

Paliotan ® Orange L 2935<br />

Paliotan ® Red L 3735<br />

Paliotan ® Yellow L 2045<br />

Paliotan ® pigments are suitable for both industrial polyester<br />

<strong>powder</strong> <strong>coating</strong>s and a large number of systems for interior use<br />

(mixed polyester or hybrids). With Primid ®1 curing agents (supplied<br />

by EMS-Chemie) we recommend performing stability tests<br />

first. The yellow and red grades should not be used in pure<br />

epoxy systems or together with matt curing agents. The heat<br />

resistance of Paliotan ® pigments is limited because of the raw<br />

materials used. If they are to be applied at temperatures significantly<br />

above 180 °C, preliminary tests should be performed in<br />

the intended application medium.<br />

Paliotol ® / Paliogen ®<br />

Organic pigments<br />

Paliotol ® pigments<br />

Paliotol ® is BASF’s trademark for organic pigments of different<br />

chemical compositions. The products described below are<br />

particularly suitable for use in <strong>powder</strong> <strong>coating</strong>s. Grades with high<br />

hiding power and good dispersibility are distinguished by the<br />

letters HD (hiding, dispersibility) following the numerical code.<br />

• Paliotol ® Yellow and Orange grades are ideal partners for the<br />

Sicopal ® and Sicotan ® Yellow pigments, because they allow<br />

the formulation of brilliant shades with good hiding power.<br />

Such combinations have often been successfully used as<br />

“lead substitution solutions”.<br />

• The Paliotol ® HD grades are particularly recommended for use<br />

in full shades. In medium and strong reductions with titanium<br />

dioxide there may be a substantial decrease in fastness to<br />

weathering. <strong>We</strong> therefore recommend minimizing the amount<br />

of titanium dioxide in the formulation and maximizing the<br />

amount of Sicotan ® Yellow (nickel or chromium titanate) or<br />

Sicopal ® Yellow (bismuth vanadate).<br />

• Paliotol ® Yellow L 0962 HD is characterized by its brilliant,<br />

greenish hue. It is ideal in combination with Sicotan ® and<br />

Sicopal ® Yellow grades. Since it has limited fastness to<br />

weathering, especially if used together with large amounts<br />

of titanium dioxide, it is not recommended for architectural<br />

<strong>coating</strong>s. Paliotol ® Yellow L 0962 HD is a pigment for full<br />

shades. Shading should be carried out with a product such<br />

as Sicopal ® Yellow L 1100/L1120.<br />

• Paliotol ® Yellow L 2140 HD is the most significant reddish<br />

yellow pigment for <strong>powder</strong> <strong>coating</strong>s. Selling points are its<br />

high hiding power and good fastness to weathering.<br />

• Paliotol ® Yellow L 2146 HD has further extended the coloristic<br />

spectrum. It is <strong>more</strong> chromatic and slightly redder in hue than<br />

Paliotol ® L 2140 HD. The application properties and fastness<br />

profile are comparable to those of Paliotol ® L 2140 HD.<br />

• Paliotol ® Yellow L 1820 is the transparent version of Paliotol ®<br />

Yellow L 2140 HD. Where high color strength is a priority in<br />

pigment selection, Paliotol ® Yellow L 1820 is the right choice.<br />

• In terms of application and coloristic properties, Paliotol ®<br />

Yellow L 1970 falls between Paliotol ® L 1820 and Paliotol ®<br />

L 2140 HD. Coloristically it comes closest to a P.Y. 83 (diaryl<br />

pigment). However, diaryl pigments are known to decompose<br />

at temperatures above 200 °C, such as may occur in polymers<br />

during processing. It has been found that temperatures above<br />

200 °C are also reached when <strong>powder</strong> <strong>coating</strong>s are being<br />

processed.<br />

• Paliotol ® Yellow L 1155 is characterized by very high color<br />

strength. To develop its full potential, it can be combined with<br />

Sicotan ® Yellow pigments. Paliotol ® Yellow L 1155 is particularly<br />

recommended for interior use. It does not cause plate-out<br />

and in full yellow shades it can also be considered for outdoor<br />

applications. Where a particularly high standard of fastness to<br />

weathering is required, preliminary tests should be carried<br />

out. On the other hand, Paliotol ® Yellow L 1155 is not suitable<br />

Recommended standard grades for <strong>powder</strong> <strong>coating</strong>s:<br />

Paliotol ® Yellow L 0962 HD P.Y. 138<br />

Paliotol ® Yellow L 1155 P.Y. 185<br />

Paliotol ® Yellow L 1820 P.Y. 139<br />

Paliotol ® Yellow L 2140 HD P.Y. 139<br />

Paliotol ® Yellow L 2146 HD P.Y. 139<br />

Paliotol ® Orange L 2930 HD P.O. 67<br />

Paliotol ® Yellow L 1970 P.Y. 139


Paliogen ® pigments<br />

as a tinting and shading pigment. It shows shade shift at<br />

temperatures above 180 °C and on overbaking.<br />

• Paliotol ® Orange L 2930 HD is a pigment with a very pure<br />

orange hue and good fastness to weathering in full shades.<br />

A formulation based on Paliotol ® L 2930 HD and Sicotan ®<br />

Yellow L 1910 (for example, for RAL 2004) is much <strong>more</strong><br />

weather-resistant than a formulation based on titanium<br />

dioxide. Paliotol ® L 2930 HD is also a pigment for full shades<br />

and therefore not suitable as a tinting and shading pigment in<br />

<strong>powder</strong> <strong>coating</strong>s. At baking temperatures above 180 °C, its<br />

suitability should first be determined in preliminary tests.<br />

None of the Paliotol ® grades we recommend is based on diaryl<br />

pigment chemistry. Diaryl pigments can decompose in polymers<br />

processed at temperatures above 200 °C.<br />

Isoindoline pigments are not suitable for use in amine- or amidecuring<br />

<strong>powder</strong> <strong>coating</strong> systems.<br />

Paliogen ® is BASF’s trademark for organic pigments of different<br />

chemical compositions and a high standard of fastness. Very high<br />

heat resistance, high hiding power and a pure hue are the outstanding<br />

features of Paliogen ® Red L 3910 HD. It can even be<br />

applied in a directly heated oven. In reductions with titanium<br />

dioxide, the fastness to weathering of Paliogen ® L 3910 HD falls<br />

significantly so that we do not recommend it for this application.<br />

• Paliogen ® Red K 4180 offers outstanding heat resistance and<br />

extremely good fastness to weathering, both in full shades and<br />

in reductions with titanium dioxide.<br />

• Paliogen ® Red L 4120 shows the same exceptional fastness<br />

properties as Paliogen ® Red K 4180 but does not attain its high<br />

standard of dispersibility.<br />

• Paliogen ® Red Violet K 5011 has distinctly <strong>more</strong> color strength<br />

and is <strong>more</strong> weather-resistant than red-violet pigments based<br />

on quinacridone. It has a high standard of heat resistance and<br />

dispersibility, but it does not offer the coloristic scope of<br />

quinacridone pigments with regard to chromaticity.<br />

• Paliogen ® Blue L 6470 has a much redder hue than Heliogen ®<br />

Blue L 6700 F. One of its uses in <strong>powder</strong> <strong>coating</strong>s is tinting<br />

white <strong>powder</strong>s. A purer white is obtained than with titanium<br />

dioxide alone. Paliogen ® Blue L 6470 has excellent fastness to<br />

weathering even at low concentrations. However, because the<br />

pigment particles are relatively hard, Heliogen ® Blue L 6700 F<br />

may in many cases be the better choice.<br />

Heliogen ® pigments<br />

Heliogen ® is BASF’s trademark for copper phthalocyanine pigments.<br />

The ranges for <strong>coating</strong>s and for plastics comprise a<br />

large number of individual products, each characterized by very<br />

specific application properties. The Colour Index (C.I.) provides<br />

an initial indication for selection purposes. The following types<br />

are distinguished:<br />

• P.B. 15 copper phthalocyanine, unstable<br />

• P.B. 15:1 copper phthalocyanine, alpha stable<br />

• P.B. 15:2 copper phthalocyanine, alpha stable<br />

and surface-treated<br />

• P.B. 15:3 copper phthalocyanine, beta<br />

• P.B. 15:4 copper phthalocyanine, beta<br />

and surface-treated<br />

• P.B. 15:6 copper phthalocyanine, epsilon<br />

Extensive trials with these pigments in <strong>powder</strong> <strong>coating</strong>s have<br />

shown that the unstabilized grades are not sufficiently heatresistant<br />

and can lead to shade changes. Processing surfacetreated<br />

pigments of the type developed for conventional <strong>coating</strong><br />

systems brings no improvement, though Heliogen ® Blue L 6700 F<br />

is an exception.<br />

Both P.B. 15:1 and P.B. 15:3 have proved very satisfactory.<br />

The Colour Index alone is insufficient to assess the suitability<br />

of a pigment for <strong>powder</strong> <strong>coating</strong>s. Very significant in ensuring<br />

good dispersibility and color strength development is the surface<br />

finish of the pigment. This is applied in a process step by the<br />

manufacturer and to a considerable extent determines the<br />

specific application properties.<br />

Heliogen ® Blue pigments<br />

Heliogen ® Blue K 6907 is a new, readily dispersible, very costefficient<br />

P.B. 15:1 pigment.<br />

Heliogen ® Blue K 6911 D, because of its good dispersibility, is<br />

our special recommendation for <strong>powder</strong> <strong>coating</strong>s. Heliogen ® Blue<br />

L 6930 is comparable in coloristic and application properties<br />

to Heliogen ® Blue K 6911 D. Quality control of Heliogen ® Blue<br />

L 6930 is carried out in a conventional <strong>coating</strong> system. The<br />

special quality control (plastics test method) used for Heliogen ®<br />

Blue K 6911 D is much <strong>more</strong> like the <strong>powder</strong> <strong>coating</strong> manufacturing<br />

process than the <strong>coating</strong>s test method.


Recommended standard grades for <strong>powder</strong> <strong>coating</strong>s:<br />

Heliogen ® Green L 8730 P.G. 7<br />

Heliogen ® Green L 8731 P.G. 7<br />

Heliogen ® Green K 9360 P.G. 36<br />

Heliogen ® Green pigments<br />

Our first recommendation for a P.B. 15:3 pigment is Heliogen ®<br />

Blue K 7090, since it shows better dispersibility than most other<br />

products in the market.<br />

Heliogen ® Blue L 7072 D and Heliogen ® Blue L 7080 offer<br />

excellent performance in <strong>powder</strong> <strong>coating</strong>s. Heliogen ® Blue<br />

K 7090 is BASF’s best dispersing beta blue pigment.<br />

Despite exceptional fastness properties, even phthalocyanine<br />

blue pigments have application limits. For example, strong<br />

oxidizing agents such as 70 % nitric acid and hydrogen peroxide<br />

decolorize the colored <strong>coating</strong> and destroy the phthalocyanine<br />

blue pigment. A nitric acid test is described, for example, in US<br />

specification AAMA 2604-02, item 7.7.3.<br />

(AAMA = American Architectural Manufacturers Association)<br />

Among the phthalocyanine green pigments, a distinction is made<br />

between bluish (P.G. 7) and yellowish (P.G. 36) green types. The<br />

recommended pigments fulfill the technical requirements with<br />

respect to heat resistance, fastness to weathering and dispersibility<br />

to a very high degree.<br />

Heliogen ® Green L 8730 is the universal standard pigment for<br />

<strong>coating</strong>s. Where suitability for both <strong>powder</strong> <strong>coating</strong>s and conventional<br />

<strong>coating</strong>s is required, Heliogen ® L 8730 is the best<br />

choice. However, the best pigment for exclusive use in <strong>powder</strong><br />

<strong>coating</strong>s is Heliogen ® Green L 8731, since it was designed for<br />

this application.<br />

The high degree of halogenation of phthalocyanine green pigments<br />

<strong>make</strong>s them much <strong>more</strong> resistant to strong oxidizing<br />

agents than phthalocyanine blue pigments.<br />

Variocrom ® / Paliocrom ®<br />

Color Variable Pigments and effect pigments<br />

Variocrom ® Color Variable Pigments<br />

The Color Variable Pigments Variocrom ® Magic Gold L 1400<br />

and Variocrom ® Magic Red L 4420 consist of an SiO 2 -coated<br />

aluminum core to which an iron oxide layer has been applied<br />

by chemical vapor deposition (CVD). Variocrom ® Magic Purple<br />

L 5520 is a Color Variable Pigment based on a lamellar iron<br />

oxide. Variocrom ® Magic Green K 9811 complements the range<br />

into green.<br />

Variocrom ® Color Variable Pigments can also be used in<br />

<strong>powder</strong> <strong>coating</strong>s. They are heat-resistant and very weatherfast.<br />

Correct processing of Variocrom ® Color Variable Pigments<br />

is vital to ensure brilliant color effects in <strong>powder</strong> <strong>coating</strong>s.<br />

Due to their lamellar form, Variocrom ® Color Variable Pigments<br />

are not resistant to the effects of high shear or impact forces<br />

that may occur in extrusion or subsequent grinding.<br />

Powder <strong>coating</strong>s are best manufactured by the bonding process,<br />

which begins with the production of a conventionally colored<br />

<strong>powder</strong> <strong>coating</strong>. After extrusion and grinding, the appropriate<br />

amount of effect pigment is added. The <strong>powder</strong> is homogenized<br />

in a temperature-controlled reactor under the action of accurately<br />

defined shear forces. This process yields a homogeneous<br />

<strong>powder</strong> <strong>coating</strong> in which the effect pigment particles are tightly<br />

bonded to the <strong>powder</strong> <strong>coating</strong> particles.


Paliocrom ® effect pigments<br />

Since the effect pigment cannot separate from the <strong>powder</strong> <strong>coating</strong><br />

particles during spraying, the result is a defect-free surface.<br />

Further<strong>more</strong>, industrially processed <strong>powder</strong>s can be reused<br />

without any significant change in shade. Bonding may be carried<br />

out in suitable mixing equipment, but is also offered as a service<br />

by companies such as Benda-Lutz (Traismaur, Austria). Plant<br />

trials involving the production of large numbers of colorations<br />

have shown that application rates between 3 % and 6 % on the<br />

overall formulation result in the most interesting shades.<br />

Paliocrom ® effect pigments have a variety of physical structures,<br />

but a common feature is their flake-like morphology. Paliocrom ®<br />

Copper L 3011, Paliocrom ® Copper L 3101 (lamellar iron oxide)<br />

and Paliocrom ® Blue Silver L 6001 (mica pigment coated with<br />

reduced titanium oxides and titanium nitride) offer additional<br />

coloring and effect possibilities. Paliocrom ® Copper L 3101 is<br />

somewhat <strong>more</strong> bluish in hue than Paliocrom ® Copper L 3011<br />

and exhibits a <strong>more</strong> pronounced sparkle effect. These pigments<br />

can be combined with organic and inorganic pigments to produce<br />

further new colors and effects.<br />

Technical data on the dyes can be found in the<br />

Organic dyes<br />

Neozapon ® dyes<br />

In contrast to pigments, dyes are soluble in the application<br />

medium. In <strong>powder</strong> <strong>coating</strong>s, the melted resin assumes the<br />

function of a solvent. Highly transparent, brilliant colorations<br />

are obtained. Application rates are typically in the 0.1 % to<br />

1 % range.<br />

The limited light fastness of Neozapon ® dyes limits their use in<br />

exterior applications. There are nonetheless a number of practical<br />

applications where Neozapon ® dyes can demonstrate their<br />

coloristic potential. For example, <strong>powder</strong> <strong>coating</strong>s are being<br />

increasingly used in the bicycle and motorcycle industry.


<strong>We</strong>ll-tried Thermoplast grades:<br />

Thermoplast dyes<br />

Neozapon ® dyes provide some interesting styling possibilities<br />

and give rise to unusual fashion trends. Dyes can also display<br />

their transparent color effects on substrates other than metals.<br />

The difference in brilliance and transparency compared with pigments<br />

is especially apparent on glass (e.g., bottles and flacons).<br />

Thermoplast dyes are based on polycyclic compounds. Unlike<br />

metal-complex dyes, they are heavy-metal-free. Distinctive<br />

application features are their high brilliance and excellent heat<br />

resistance. However, they have limited light fastness.<br />

Laropal ® A / Uvinul ® / Acronal ® / Luwax ®<br />

Additives and auxiliaries<br />

Laropal ® A<br />

Uvinul ®<br />

Laropal ® A 81 and Laropal ® A 101 are hard resins based on<br />

isobutyraldehyde. They are used as cobinders and can be added<br />

to <strong>powder</strong> <strong>coating</strong>s to improve properties such as film hardness<br />

and pigment wetting (10 - 15 %). Addition of approx. 15 %<br />

Laropal ® A 101 (relative to the amount of binder) considerably<br />

reduces the “bronzing” of dark blue shades based on phthalocyanine<br />

blue.<br />

Uvinul ® 4050 H is a sterically hindered amine light stabilizer<br />

(HALS). Its effect in <strong>powder</strong> <strong>coating</strong>s is based on the stabilization<br />

of electric charge, especially in the application of frictional<br />

charging or tribotechnology. Uvinul ® 4050 H is incorporated with<br />

the other raw materials at an application rate of 0.3 to 0.5 %.


Acronal ®<br />

Luwax ®<br />

Acronal ® 4 F is a butyl acrylate polymer. It resists saponification<br />

and has excellent fastness to light and weathering. Acronal ® 4 F<br />

is used in <strong>powder</strong> <strong>coating</strong>s as a flow agent. The product is very<br />

viscous and cannot be incorporated directly into <strong>powder</strong> <strong>coating</strong>s<br />

as supplied. It is applied in the form of a masterbatch or precipitated<br />

on silicate.<br />

The Luwax ® grades are homopolymeric polyethylene waxes.<br />

They are supplied as <strong>powder</strong>s (A grades) and micro<strong>powder</strong>s<br />

(AF grades). Micronized polyethylene waxes are finely pulverized<br />

with a particle size in the micron range. BASF’s micronized wax<br />

<strong>powder</strong>s have a characteristic spherical shape resulting from<br />

their manufacture. Waxes can be used in <strong>powder</strong> <strong>coating</strong>s as<br />

lubricants, flow agents and release agents.<br />

They improve the scratch resistance, antiblocking properties,<br />

pourability of the <strong>powder</strong> <strong>coating</strong> mixture and flowability of the<br />

<strong>powder</strong> <strong>coating</strong> melt in the extruder. A typical application rate<br />

is 1 to 3 %.<br />

For <strong>powder</strong> <strong>coating</strong>s we recommend the<br />

following grades:<br />

Luwax ® AM 3<br />

Luwax ® AM 6<br />

Luwax ® AH 6<br />

Luwax ® AF 31<br />
