Reolosil® QS-30 is a very fine amorphous silicon dioxide made by the combustion of high-purity silicon tetrachloride with oxygen and hydrogen. Its unique properties offer advantages in many applications: silicone rubber, sealants, organic elastomers, UPR, adhesives, paint, ink, and free flow. It is used as a reinforcing, thickening, anti-settling, thixotropic, and free flow agent.
