HB-151
Characteristics
HB-151 is hydrophobic fumed silica which is produced by HL-150 after chemical post-treatment with DDS(Dimethyldichlorosilane).
Applications
RTV silicone rubber,especially RTV-T
Adhesives & Sealants
Coatings & Printing ink
Powder Coating
Properties
Thixotropy and reinforcement in RTV silicone sealants, the hydrophobic feature gives RTV silicone sealants a long shelf-life
Rheology control in adhesives
Anti-settling, anti-sagging and thixotropy control
Free flow aid and anti-caking aid for powders
