HEXAFILL is medium whiteness Calcined kaolin produced by high temperature treatment of premium quality kaolin. Calcinations process develops micro porous surface, which enhances light scattering and improves optical properties of the finished product.
HEXAFILL is recommended in the paint industry as a partial substitute of Titanium Dioxide for improved opacity.
