Fumed silica is manufactured via a dry process of combustion hydrolysis in the gas state. The primary particles consist of nano-size flakes. Fumed silica, structurally, has no gap among particles and is weakly agglomerated together with minimal internal surface area.
Fumed silica is traditionally utilized for rheological purposes. The Rheology control function includes thickening (bodying), Thixotropy, Anti-sag, Hold out, Edge coverage and Pattern control in metallic finishes. The coating uniformity is improved by preventing the pigment stratification during the curing, even at high temperatures.
20 Microns offers a range of Fumed Silica based on the Viscoity and rheology demanded in end formulation for industries like Paints and coating, plastics, Textiles, Adhesives, Construction chemicals etc.
