XYSIL, a synthetic amorphous pyrogenic(fumed) silica, is applied as a thickening and thixotropic agent in many organic systems, e.g. in Unsaturated Polyesters, Coatings, Paint, Printing inks, Adhesive, Sealant and others. It is used as a reinforcing filler in elastomers, mainly RTV silicone and HTV silicone. It acts as a free flow additive in the production of technical powders.

XYSIL fumed silica can be used in different applications and can replace Aerosil and Cabosil’s hydrophilica products in some fields, for details please contact us or download XYSIL Fumed Silica Application And Selection Guide
