ZH-135
Characteristics
ZH-135 is a hydrophobic fumed silica which is created by subjecting hydrophilic grades with BET of 380m2/g to chemical post-treatment with HMDS (Hexamethyldisilazane).
Properties
Low thickening effect and excellent processability enable high loading in polymers
Excellent reinforcing properties in silicone rubber especially at high filler loading levels(RTV-1,RTV-2,LSR)
Well suited for transparent systems
Free-flow aid for powders
Applications
Silicone rubber; Adhesives and Sealants; Defoamer; Toner
ZH-151
Characteristics
ZH-151 is a hydrophobic fumed silica which is created by subjecting hydrophilic grades with BET of 150m2/g to chemical post-treatment with DDS(Dimethyldichlorosilane).
Applications
RTV silicone rubber,especially electronic potting and Liquid glue; Adhesives and 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
ZH-152
Characteristics
ZH-152 is a hydrophobic fumed silica which is created by subjecting hydrophilic grades with BET of 200m2/g to chemical post-treatment with DDS(Dimethyldichlorosilane).
Applications
RTV silicone rubber,especially electronic potting and Liquid glue
Adhesives & Sealants
Coatings, Printing ink
Properties
Higher hydrohpobicity, thixotropy, thickening, transparency and reinforcement
Thixotropy and reinforcement in RTV silicone sealants, the hydrophobic feature gives RTV silicone sealants a long shelf-life
Anti-settling,anti-sagging,thixotropy and Rheology control in adhesives
Free flow aid and anti-caking aid for powders
ZH-630
Characteristics
ZH-630 is a hydrophobic fumed silica which is created by subjecting hydrophilic grades with BET of 380m2/g to chemical post-treatment with HMDS (Hexamethyldisilazane).
