Paliotol ® / Paliogen ® Organic pigments Paliotol ® pigments Paliotol ® is BASF’s trademark for organic pigments of different chemical compositions. The products described below are particularly suitable for use in powder coatings. Grades with high hiding power and good dispersibility are distinguished by the letters HD (hiding, dispersibility) following the numerical code. • Paliotol ® Yellow and Orange grades are ideal partners for the Sicopal ® and Sicotan ® Yellow pigments, because they allow the formulation of brilliant shades with good hiding power. Such combinations have often been successfully used as “lead substitution solutions”. • The Paliotol ® HD grades are particularly recommended for use in full shades. In medium and strong reductions with titanium dioxide there may be a substantial decrease in fastness to weathering. We therefore recommend minimizing the amount of titanium dioxide in the formulation and maximizing the amount of Sicotan ® Yellow (nickel or chromium titanate) or Sicopal ® Yellow (bismuth vanadate). • Paliotol ® Yellow L 0962 HD is characterized by its brilliant, greenish hue. It is ideal in combination with Sicotan ® and Sicopal ® Yellow grades. Since it has limited fastness to weathering, especially if used together with large amounts of titanium dioxide, it is not recommended for architectural coatings. Paliotol ® Yellow L 0962 HD is a pigment for full shades. Shading should be carried out with a product such as Sicopal ® Yellow L 1100/L1120. • Paliotol ® Yellow L 2140 HD is the most significant reddish yellow pigment for powder coatings. Selling points are its high hiding power and good fastness to weathering. • Paliotol ® Yellow L 2146 HD has further extended the coloristic spectrum. It is more chromatic and slightly redder in hue than Paliotol ® L 2140 HD. The application properties and fastness profile are comparable to those of Paliotol ® L 2140 HD. • Paliotol ® Yellow L 1820 is the transparent version of Paliotol ® Yellow L 2140 HD. Where high color strength is a priority in pigment selection, Paliotol ® Yellow L 1820 is the right choice. • In terms of application and coloristic properties, Paliotol ® Yellow L 1970 falls between Paliotol ® L 1820 and Paliotol ® L 2140 HD. Coloristically it comes closest to a P.Y. 83 (diaryl pigment). However, diaryl pigments are known to decompose at temperatures above 200 °C, such as may occur in polymers during processing. It has been found that temperatures above 200 °C are also reached when powder coatings are being processed. • Paliotol ® Yellow L 1155 is characterized by very high color strength. To develop its full potential, it can be combined with Sicotan ® Yellow pigments. Paliotol ® Yellow L 1155 is particularly recommended for interior use. It does not cause plate-out and in full yellow shades it can also be considered for outdoor applications. Where a particularly high standard of fastness to weathering is required, preliminary tests should be carried out. On the other hand, Paliotol ® Yellow L 1155 is not suitable Recommended standard grades for powder coatings: Paliotol ® Yellow L 0962 HD P.Y. 138 Paliotol ® Yellow L 1155 P.Y. 185 Paliotol ® Yellow L 1820 P.Y. 139 Paliotol ® Yellow L 2140 HD P.Y. 139 Paliotol ® Yellow L 2146 HD P.Y. 139 Paliotol ® Orange L 2930 HD P.O. 67 Paliotol ® Yellow L 1970 P.Y. 139
Paliogen ® pigments as a tinting and shading pigment. It shows shade shift at temperatures above 180 °C and on overbaking. • Paliotol ® Orange L 2930 HD is a pigment with a very pure orange hue and good fastness to weathering in full shades. A formulation based on Paliotol ® L 2930 HD and Sicotan ® Yellow L 1910 (for example, for RAL 2004) is much more weather-resistant than a formulation based on titanium dioxide. Paliotol ® L 2930 HD is also a pigment for full shades and therefore not suitable as a tinting and shading pigment in powder coatings. At baking temperatures above 180 °C, its suitability should first be determined in preliminary tests. None of the Paliotol ® grades we recommend is based on diaryl pigment chemistry. Diaryl pigments can decompose in polymers processed at temperatures above 200 °C. Isoindoline pigments are not suitable for use in amine- or amidecuring powder coating systems. Paliogen ® is BASF’s trademark for organic pigments of different chemical compositions and a high standard of fastness. Very high heat resistance, high hiding power and a pure hue are the outstanding features of Paliogen ® Red L 3910 HD. It can even be applied in a directly heated oven. In reductions with titanium dioxide, the fastness to weathering of Paliogen ® L 3910 HD falls significantly so that we do not recommend it for this application. • Paliogen ® Red K 4180 offers outstanding heat resistance and extremely good fastness to weathering, both in full shades and in reductions with titanium dioxide. • Paliogen ® Red L 4120 shows the same exceptional fastness properties as Paliogen ® Red K 4180 but does not attain its high standard of dispersibility. • Paliogen ® Red Violet K 5011 has distinctly more color strength and is more weather-resistant than red-violet pigments based on quinacridone. It has a high standard of heat resistance and dispersibility, but it does not offer the coloristic scope of quinacridone pigments with regard to chromaticity. • Paliogen ® Blue L 6470 has a much redder hue than Heliogen ® Blue L 6700 F. One of its uses in powder coatings is tinting white powders. A purer white is obtained than with titanium dioxide alone. Paliogen ® Blue L 6470 has excellent fastness to weathering even at low concentrations. However, because the pigment particles are relatively hard, Heliogen ® Blue L 6700 F may in many cases be the better choice.
