Hydrophobic Fumed Silica Powder HS CODE:281122 As White and Colloidal Powder
Description
HB-151 Hydrophobic fumed silica is produced by the chemical modification of hydrophilic with reactive silanes, e.g. chlorosilanes or hexamethyldisilazane. It has water-repellent properties and is no longer dispersible in water. This hydrophobic fumed silica Powder provide superior performance benefits for many types of applications, including: Adhesives and sealants, Coating, Silicone sealants.
Feature
A, Reduced moisture adsorption
B, Anti-settling, thickening and sag resistance in polar systems
C, Scratch and abrasion resistance
D, Free-flow and anti-caking
E, Corrosion resistance
