HB-612
Characteristics
HB-612 is hydrophobic fumed silica which produced by HL-150 after chemical post-treatment with HMDS (Hexamethyldisilazane).
Applications
RTV silicone sealants,especially electronic potting and Liquid glue
Adhesives and Sealants
Coatings & Printing ink
Powder Coatings
Properties
Thixotropy and reinforcement in RTV silicone sealants, the hydrophobic
feature gives RTV silicone sealants a long shelf-life
Rheological control of RTV silicone rubber
Anti-settling,anti-sagging and thixotropy agent
Free flow aid and anti-caking aid for powders
