General physical property

REOLOSIL QS­20LS is a very fine particle size obtained by burning high purity silicon tetrachloride in an oxyhydrogen flame.

Silica. Its unique properties give more advantages to products in many fields; such as UPR, adhesives, paints, inks and fluid powders.


It is used as a thickener, anti-settling agent, thixotropic agent and fluidizer.

Special physical property

Large specific surface area and small particle size

Original particle size: about 12 nm

General packaging form
