WACKER HDK H 15 Fumed Silica is a hydrophobic fumed silica formed by a chemical reaction of hydrophilic WACKER HDK팜 with organosilanes. Hydrophilic fumed silica is produced by flame hydroloysis of volatile silicon compounds. H 15 is a pure, x-ray amorphous silicon dioxide (SiO2).
* Free-flow agent especially for moisture sensitive substances(e.g.,peroxides, pigments, PPC-toners)
* Reinforcing filler and thichening agent for RTV-1 silicone sealants, polysulfides, polyurethanes, and acrylates
* Antisettling agent in zinc-rich paints and printing inks |
