Fumed SiO2

Fumed SiO2 1.Used in silicon rubber, construction sealant 2.Used in printing acid rubber, powder coating 3.Net weight 10kg

Fumed Silica

Characteristic: It is a white and colloidal micro-particle with its primary micro-particle from 5-40 nm and has obvious properties such as thixotropy, reinforcing, thickening and filling etc. and is insoluble in all kinds of solvents and liquids except hydrofluoric acid and concentrated bases.

If applied as good dispersant in coating, it improves the suspension stability and processing performance of coatings . Overseas, it has been plentifully in cosmetics, agricultural seed protective agent, pharmaceutical carrier and top coat of high-grade car. It has been applied in polishing agent of electronic PCB in developed countries, also with great application amount in ROK, Japan and Taiwan in Asia.
