Silica Precipitation Matting Agent

Silica Precipitation Matting Agent, precipitated matting agent

Brief Introduction:
This series of matting powder is produced base on the precipitation method. That is silica precipitates after adding acid to the silica gel in the salt solution. It's tasteless, non-toxic, non-flammable, villous and only soluble in hydrofluoric acid and alkali. No change color nor decomposition after exposure at the high temperature or under sunlight.
We have silica precipitation series as follow: WL-200, WL-201, WL-202, WL-203, TS-30, TS-301. WL-200 & WL-202 are produced through organic surface treatment, which improve the paint film's transparency and dispersity. TS-30 & TS-301 are produced through organic wax surface treatment, which give the product better suspension and redispersibility.

Main Features:
1. High extinction efficiency
Advanced production process lead to narrow size distribution, so that to increase the flatting efficiency.
2. Excellent paint film
Benefit from higher purity of Silica and organic wax surface treatment, our matte powder enable paint film to have excellent appearance, transparency, wear-resistance and anti-scratch.
3. Super dispersity
With advanced grinding technology, the powder has super dispersion which could be added into any process of coating production.
4. Perfect performances of suspension
Owing to the organic wax surface treatment, there's no hard sedimentation even after long storage in the low viscosity varnish.
