Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments. Its appearance is white powder. Native particle size ranges from 5nm to 40nm, with significant functions of thixotropy, reinforcing, thickening and filling. Therefore, it is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.
1.As a liquid thixotropic agent and thickener, precipitation, prevent sagging prevention
2.Improved paint filler suspension and dispersion in liquid system
3. Dispersion and grinding AIDS
4.Cardiac liquidity powder, stability
5.Cardiac improve the film scratch resistance
6.Cardiac improve colorful
7.Cardiac fixed special effects
8. Cardiac viscoelastic can improve rubber, elastomers, reinforcement
9.Derive the defoaming role of defoaming agent
10. Cardiac improve coating surface hardness, resistance to scratch
11.His film and elastomer in preventing adhesion
