This silica matting agent for waterborne coatings is specially treated with organic surface modification. It features high porosity, which can significantly improve matting efficiency and deliver excellent transparency. Its good hydrophilicity leads to better dispersion and excellent suspension properties, allowing the matting agent to be dispersed more easily in aqueous systems. Meanwhile, the cured film exhibits a delicate and smooth hand feel.
