A New Way to Add Value to Your Products

Soltex now offers fumed silica (also called pyrogenic silica or colloidal silica, SiO2), a low-density, high-surface-area powder.

A Versatile Additive

Fumed silica is an excellent thickener and reinforcing filler for coatings, adhesives, sealants, elastomers, lubricants, greases, and more.

It also imparts rheopexy, anti-settling, anti-blocking, dispersing, fluidity, and anticorrosive properties to your products.
