Hydrophobic Fumed Silica R620


Description:
HJSIL R620 is a hydrophobic fumed silica after-treated with Hexamethyldisilazane (HMDS). It is a Hydrophobic fumed silica treated. 


Hydrophobic fumed silica HJSIL R620 is made by in-situ surface modification of powder by using special imported additives and nanotechnology. Mainly used as silicone rubber reinforcing agent, plastic filler, and thickener for coatings and inks. Different from untreated nano-silica, the lipophilic nano-silica powder has better interfacial compatibility with the substrate resin, can be evenly dispersed in the substrate resin, and form a close bond with the polymer system, improving the overall properties of polymer materials.


Aerosil Fumed Silica Applications:
HTV Silicone Rubber 
Liquid Silicone Rubber (LSR) 
Coatings and Inks 
Adhesives and Sealants 
Powder Coatings
