OptiMat® 2550

OptiMat® 2550 by Imerys is a specially formulated, natural mineral additive designed as a matting agent in decorative paints. It is effective as little as 3% by weight in a matt formulation and gives 85° sheen below 1.0%. This fine particle size grade offers smooth surface texture to low-loaded coatings. It provides high paint whiteness and increased mudcrack resistance. Mineral hardness of OptiMat® 2550 contributes to excellent burnish- and scratch resistance.
