Commonly known as hydrous kaolin, this clay based mineral is the layered form of silicate mineral. White China Clay Powder is free from odor. It shows inertness when exposed to chemicals. Excellent chemical resistance properties, crack prevention capacity, unique opacity level and ability to maintain smoothness of applied surface are its key features. Better scrub resistance properties, good shear thinning attributes, rust proof and exceptional tinting strength are some of its main factors. It easily dissolves in water based paints. Its properties can be modified by calcinations process under more than 1100 degree C temperature. Calcination improves abrasion resistance capacity, whiteness and hardness of china clay. Calcined clay is preferred for formulation of matt based coatings and paints.
This powder is basically formed as a result of chemical weathering of feldspar. As part of its other production procedures, it is excavated from rocks and then its impurities are washed (to be precise, eluriated) by applying water. Large sized rock particles containing kaolin are sorted and dried.
