Fumed Silica

HB- Hydrophobic Fumed Silica HB-612 0 612

Characteristic

FM-H-B612 is hydrophobic fumed silica which produced by hydrophilic fumed silica with specific surface

Area of 150m²/g after chemical post-treatment with HMDS (Hexamethyldisilazane)

Applications	Properties
● RTV silicone rubber	● Rheological control of RTV silicone rubber
● Adhesives & sealants	● Anti-settling,anti-sagging and thixotropy agent
● Coatings & Printing Ink	● Free flow aid and anti-caking aid for powders
● Powder Coating	● Thixotropy agent & reinforce filler for RTV silicone sealants, the hydrophobic feature enables RTV silicone sealants a long guarantee time
