Abstract
This invention is about organic 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.
