KW®Anti-Yellowing Series

Conventional silver white pearl pigments have TiO2 coated on the surface of mica substrate, due to the photoactivity of TiO2 and its catalyzed reaction with phenolic antioxidants, when they are used for plastics applications, the final products may turn to yellowing after some time. 
KW®KH6*** series was developed in order to avoid the above problems, and enhances the performance of silver white pearl pigments in plastics applications. KW®KH6119 and KW®KW6123 received technical approval from L’oreal for materials and substances in their packaging. 
All conventional silver white products can be made to their corresponding anti-yellowing versions.
