SP-OF3472B Polymeric Dispersant

SP-OF3472B is a polymeric surfactant with comb structure, copolymerized using unsaturated monomers. Its highly solvated side chain maintains the compatibility of the particles and continuous phase. At the same time, the high charge density of side chain enhances its multiple-point adsorption to particle surfaces. The product is designed to be used in combination with SP-OF3468 Emulsifier to facilitate the grinding process and improve the stability of formulations.
