Hydrophobic Fumed Silica Powder HS Code: 281122 As White Powder Used For RTV Silicone Sealants
Characteristics
HB-151 is a hydrophobic fumed silica after treated with DDS(Dimethyl based on a hydrophilic fume silica with a specific surface area of 120 m2/g. It is a kind of high purity white colloidal powder.
Applications
1, RTV silicone sealants, especially electronic potting.
2, Adhesives and Sealants
3, Coatings, Inks.
4, Powder Coatings.
Properties
1, Thixotropy and reinforcement in RTV silicone sealants, the hydrophobic feature given RTV silicone sealants a long period Shelf-life.
2, Rheology Control in adhesives.
3, Improvement of anti-settling, anti-sagging and thixotropy control.
4, Improve the free flow of powder coatings and anti-caking.
