Description

AEROSIL R 812 is a fumed silica aftertreated with organosilane (HMDS) with high specific surface and marked hydrophobia.

  • The product has a large specific surface area and is very hydrophobic
  • Good flowabillty and dispersion properties
  • Excellent effect in the rheological control of complex liquid systems (such as 2K PUR coatings)
  • Because of the fineness of the particles and the very marked hydrophobia, the product acts as an excellent flow agent for fine powders up to 1 µm
