Abstract
This technology is directed to a well-dispersed micronized pigment (carbon black and/or metal oxides such as iron oxide and zinc sulfide) which is added to Aristech's acrylic solid surface formulation at 0.5-5 wt % resulting in a solid surface with an enriched color and improved surface scratch appearance. The use of the micronized pigments helps surface scratches appear less white because of the improved coverage of white aluminum trihydrate (ATH).
