Reinforcing Composites

We provide fumed silica for improved reinforcing composites used in construction applications.

We offer hydrophilic and hydrophobic fumed silica to improve the performance of laminating resins and gel coatings used in the manufacture of fiber reinforced composite products. In polyester and vinyl ester laminating resins, our fumed silica provides thixotropy that enables resin flow and fiber wetting during application. At the same time, it prevents the resin from running or sagging on slanted or vertical surfaces while the resin cures. In gel coats, our fumed silica enables thicker, non-sag coatings as well as impeding the settling of pigments and filler.
