In the case of P.Y. 139, the temperature, surfactant level and other parameters may be varied to obtain fine (Paliotol Yellow L 1820), medium size (Paliotol Yellow L 1970) and coarse products (Paliotol Yellow L 2140 HD) by selectively adjusting advanced finishing procedures and conditions.

Only coarsely crystalline pigments like Paliotol Yellow L 2140 HD are stable up to pH 8.5-9 and can be used in waterborne automotive paints. A patent describes the addition of acidic buffers to overcome the negative effects of alkaline additives in plastics. 

P.Y.139 - transparent forms The three BASF grades Paliotol Yellow D 1819, L 1820, K 1841 differ only slightly in the size of the primary particles. The final milling process, however, is directed toward the final field of application. 

Paliotol Yellow D 1819 is mainly used in NC-packaging inks. Its main merit in this field is good transparency, high colour strength and good rheological properties. 

Paliotol Yellow L1820 is mainly used in industrial paints. Its high colour strength can be combined with the good hiding power of suitable inorganic extenders to reduce pigmentation cost. 

Graphtol Yellow H2R (Clariant) is recommended for PVC, cable sheathing compounds, PO and P P spin-dying. Colouristically it is very close to Paliotol Yellow K1841. 

P.Y.139 - semiopaque form Paliotol Yellow L 1970 offers a very good compromise... 

P.Y.139 - opaque forms Paliotol Yellow L 2140 HD offers the optimum in terms of hiding power, brilliancy in full shade, outdoor durability and rheological properties, unfortunately at the expense of reduced colour strength. The pigment is the product of choice for lead-free high grade industrial and automotive OEM and refinish reddish yellow paints. It is stable even in automotive waterborne systems. On fresh concrete and similar applications, however, it cannot be used. 

P.Y. 185 Paliotol Yellow D 1155 has its main application in solvent-borne packaging inks because of its high colour strength, good transparency and excellent rheological properties. 

The influence of the finishing conditions on the size of the primary particles is obvious (Figure 19-3). Paliotol Yellow L 0960 HD being recrystallized at lower temperatures has smaller and less uniform particles than Paliotol Yellow L 0962 HD, which is finished at higher temperatures. The plastic grade K 0961 HD is similar to L 0960 HD in primary particle size, but differs in size of the agglomerates because of its different final milling process. 

Paliotol Yellow D 0960 is specifically used in metal deco and screen printing inks, where its very good light- and weather fastness is required. 

For paints, two grades are offered, differing in the size of the primary particles. Paliotol Yellow L 0960 HD has a mean particle size of - 220 nm and a specific surface area of 24.0 m /g, while L 0962 HD has particles of - 390 nm and a specific... 

This grade was replaced with Paliotol Yellow L 0960 HD, D 0960 and K 0961 HD a few years later. In 1982, a pigment with lower specific surface, better hiding power...
