Micronised silica for industrial formulation
Silica Flour
Finely ground, high-purity silica in 200 and 325 mesh grades for paints, adhesives, sealants, refractories, ceramics and oil-well cementing.
- Manufactured to: ISO 9001 process control
Overview
Silica flour is a functional filler: it adds hardness, chemical resistance and dimensional stability without adding colour. Purity and particle size distribution are what determine whether it disperses cleanly into a formulation or settles out.
