Calcit CoverPlex 75/72

Calcit CoverPlex 75/72 is a natural, wet ground calcium carbonate of exceptionally high purity. It is used as a pre-coating and coating pigment in the production of coated paper and board. The narrow particle-size distribution and extreme whiteness contribute to high coverage, glossiness and smoothness of paper and board. Suitable granulation allows the reduction of clay and other additives.
