Gas phase nano silica (white carbon black)

  CAS：7631-86-9  ■ scope of application
Vapor phase nano silica, also known as white carbon black, is a white powder in appearance
It is mainly used in silicone rubber (HTV, RTV), paint, coating, ink, electronics, papermaking, resin, adhesive, defoamer, sol, plastics, ceramics and other industries

■ application characteristics
1
Large specific surface area, good dispersibility and anti sedimentation

2
In silicone rubber: good reinforcement, wear resistance and transparency

3
In coatings: anti sagging, anti sedimentation, improving pigment stability, improving pigment dispersion, improving film adhesion, anti-corrosion, waterproof, preventing foaming, facilitating flow, and enhancing rheological control

4
It is applicable to all paint layers (adhesives, coatings, inks) to improve the stability of pigments, improve the dispersion of pigments, improve the adhesion of paint film, anti-corrosion, waterproof, anti sedimentation, and prevent foaming, especially the reinforcement of silicone rubber, adhesive thixotropic agent, and anti sedimentation agent of coloring system

5
For liquid system, it can obtain thickening, rheological control, suspension, anti sagging and other functions

6
For the solid system, it can improve the reinforcement and wear resistance

7
For the powder system, it can improve the good free flow and prevent caking
It can also be used as filler for natural and synthetic rubber, medicine and cosmetics
