SB-432 ATH developed especially for SMC, BMC, resin injection and high solids coatings, has a unique particle size distribution that provides the best possible combination of viscosity, flame, electrical and molding properties that can be derived from an ATH filler. A closely controlled top size with a large super fine faction yields rapid dispersion in resin. Excellent mold flow and wet-out characteristics result in superior surface profile, minimal porosity, even pigmentation, and excellent filler and reinforcement distribution throughout the molded part.
