HEXAFINE is an ultra-fine grade Calcined Clay produced by high temperature calcination of premium quality Kaolin. The calcination process develops micro porous surface, which enhances light scattering and improves optical properties of the finished product.
HEXAFINE is recommended as partial substitute (15-20%) for Titanium Dioxide in water based and solvent based semi-Gloss Paints for improved optical properties.
