Welcome to Imerys Performance Minerals

Calcium Carbonate & Kaolin Blends

Calcium Carbonate and Kaolin Blends

  • Single blended pigment
  • Superior brightness & gloss
  • Optimal coverage
  • Single-layer, pre-coat or top-coat applications

Imerys has invested its extensive experience in both carbonate and kaolin minerals in developing a line of ground calcium carbonate (GCC), precipitated calcium carbonate (PCC) and kaolin blended products for coating paper and board. 

These composite products are flexible in the size of both components and the ratio in which they are combined, depending on the end use. They offer paper and board producers the ability to improve coating kitchen logistics by receiving a single blended pigment.
