HN-336 is a halogen–free, medium particle size ATH product that provides low cost flame retardant and smoke suppression in a variety of applications. The particle size distribution is specifically designed for low viscosity, high filler loading levels, and excellent processing characteristics, up to 200°C. HN-336 is recommended for spray-up or hand-lay up FRP applications, filament winding, panel production, resin injection, foam materials, cast polymer and epoxy parts, coatings, adhesives, latex, vinyl and urethane compounds.
