Hermcol^® Red 3885 (Pigment Red 179)

Hermcol^® Red 3885, a dimethylperylimide compound, is probably the most significant member of its class. The pigment is primarily used in industrial coatings, especially for high grade original automotive (O.E.M) finishes and automotive refinishes. Coloristically, the pigment covers two different portions of the spectrum. On the one hand, it provides clean shades of red, with newer types producing comparatively yellowish shades. On the other hand, the pigment also affords maroon and bordeaux shades. Transparent types are available for metallic finishes, sometimes also in combination with other organic or inorganic pigments. These products extend the range of shades provided by quinacridone pigments towards the yellowish portion of the spectrum.Hermcol^® Red 3885 types demonstrate excellent weatherfastness. They are as weatherfast or even more weatherfast than substituted quinacridone pigments.Although they are used to a considerable extent in paints, Hermcol^® Red 3885 types have stimulated little interest throughout the plastics industry. The pigments are used in PVC and in PVC plastisols.
