Overview
Micronized calcium carbonate is one of the most widely used mineral fillers in paints, coatings and plastics. Its behavior in a formulation depends mainly on particle size and distribution.
Finer grades can contribute to gloss, opacity and mechanical properties. Coarser grades are used as economical extenders.
