ORGANIC POWDER FILLER USEFUL AS THE REPLACEMENT OF MINERAL FILLER IN COMPOSITES

摘要

This invention is about organic filler powder materials useful as the replacement of mineral or inorganic fillers in composites. The organic powder materials have particle size less than 60 µm and are visually non-differentiable in composites. The gel coat materials with the organic powder have uniform color appearance and have improved color stability when exposed to moisture.
