Specifications

AEROSIL® R 812 Hydrophobic Fumed Silica

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

Properties
  • The product has a large specific surface area and is very hydrophobic
  • Good flowability and dispersion properties
  • Excellent effect in the rheological control of complex liquid systems (such as 2 K 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
Applications
  • Very efficient rheological control additive and also used for thixotropy control in polar to semi-polar coating systems and in adhesive and sealant materials
  • Efficient effect as flow agent in very different applications, such as powder coatings, toners, or cosmetics
  • Enhances the anti-corrosion properties for coatings
  • To improve the storage stability of oil dispersions in agrochemicals
  • Improves the mechanical properties of various polymer systems, such as silicone rubber
  • In coatings and adhesives, AEROSIL® R 812 acts as an anti-settling agent, stabilizes pigments, and increases the anti-corrosive effect
