AEROSIL R 812

Hydrophobic fumed silica

AEROSIL R 812 - Description

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

Features

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

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
