Ostar 400
Product description
Ostar 400 is a specially processed calcined kaolin powder material, having very low impurity content, high specific surface area, porous platy structure, low conductivity, grind fineness, good dispersion stability and suspension property. It can improve the sedimentary stability and increase service life of the electrocoat bath in electrophoretic primer. It also can improve salt spray resistance, smoothness, compactness and homogeneity of the film. Ostar 400 has developed gaps, good heat insulation ability, high oil absorption and low wear. It is also widely used in thermal paper, Carbonless copy paper and other fields.
