MT-6801/MT-6801A are kinds of easily dispersible amorphous silica matting agent with big pore volume. Due to its high transparency, it is especially recommended in solvent based furniture lacquer, surface finishing. MT-6801/MT-6801A are organic treated grades and can be applied both in solvent system and aqueous system. MT-6801A has twice organic treatment and is suggested for aqueous system.
