- Recommended Application
A closely controlled top size with a large superfine fraction yields rapid dispersion in resin. Excellent mold flow and wet‐ out characteristics result in superior surface profile with minimal porosity, even pigmentation and excellent filler and reinforcement distribution throughout the molded part. HN‐434 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.
