Aerosil is a fumed silica powder that may be used for thickening materials (such as ProsAide) and matting cast silicone parts. May be used as a thickening agent for silicones and polyurethanes.

While Aerosil is a food grade additive, is a fine particle and may be a breathing hazard if suspended in the air.

Important! Sold by volume! This is a very low density powder and the container will feel empty. It is not! Open with care!!!

Use care and avoid inhalation.
