Reactive Colloidal Silica –Reactive Colloidal Silica is 99.5% pure nano-sized silica particles suspended in an ultra-low surface tension liquid. (A “colloid” is a suspension of solid particles in a liquid; the solids are not dissolved, but they do not sink to the bottom and separate, either, due to a special process.). For stone benchtop fabrication businesses and workers. Reduction in workplace exposure standard for respirable crystalline silica. The national workplace exposure standard for respirable crystalline silica (RCS) has been halved from 0.1 mg/m.
