Hydrophobic Fumed Silica Powder HS Code: 281122 Used For Adhesives of Rheology Control
Introductions
The Hydrophobic fumed silica HB-151 is a synthetic amorphous, non-crystalline silica. It is odorless, chemically inert and has no adverse health or environmental effects when used as recommend.
Characters
1, Treated with a reactive silane to give water repellent characteristics
2, Useful for thickening polar solvents and resins like alcohols, isocyanates, epoxies and urethanes
3, Useful for reinforcing silicones without thickening.
