SILICON DIOXIDE AEROGEL PRODUCTS
Silicon dioxide from sinopigments is a highly dispersed or fumed silicon dioxide, It is a white, fluffy powder, consisting of spherically shaped Primary particles. It is generally regarded as unique in industry because of its unusual particle characteristics, extremely small particle size, enormous surface area, high purity and its chain-forming tendencies set it apart in class of its own.
Silicon dioxide as a thickener and thixotrope in liquids, improves the suspension behaviour and redispersibility of solid in liquid system, dispersion and grinding aid, reinforcing filler in elastomers produces, Increases the free flow and storage stability of powders, for the production of high purity silica glass and silicates, for printer and plain paper copier toner.

SILICON DIOXIDE AEROGEL PRODUCTS
Advantages:
High efficiency
The distribution of the particle size is controlled, so flatting efficiency is increasing a lot.
High transparency
Extremely high purity, It makes silica invisible in polymer films and clear lacquer, increases flexibility, improves the ability to prevent from having chemical change and antipollution.
Easily dispersed
Easily dispersed in any coatings, only require the common high sped stirs by approximate line-velocity 5m/s, and stirring 15-20 minutes, typical hegman value 15-25um.
Super suspension
No hard sedimentation through long time reserving since it is treated.
Good compatibility
In order to keep the color of paint film, the products having surface treatment and are compatible with clear coating.
