- Packaging and Storage
25 kg paper bag and 1000 kg pallet. The product should be stored under dry and clean conditions in its original packing. The moisture content may increase if not stored under dry conditions.
- Recommended Applications
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.
