Fusil®215 is hydrophobic fumed silica after treated with DDS (Dimethyldichlorosilane) based on a hydrophilic fumed silica with a specific surface area of 150 m2/g. It’s a kind of high purity white colloidal powder. Properties - Thixotropy and reinforcement in RTV silicone sealants, the hydrophobic - Feature given RTV silicone sealants a long periods Shelf-life - Rheology control in adhesives - Improvement of anti-settling, anti-sagging and thixotropy control - Improve the free flow of powder coatings and anti-caking

Low thickening effect and excellent processability enable high loading in polymers - Good antisag properties and excellent stability in epoxies - Excellent reinforcing properties in silicone rubber applications especially at high filler loading levels and no crepe hardening on aging in silicone rubber - Well suited for transparent systems - High water resistance and free-flow aid for powders

Fusil® 200 is hydrophilic fumed silica with a specific surface area of 200 m2/g .The original particle size can be 5- 40 nm. It’s a kind of high purity white colloidal powder. Properties include - - Reinforcing filler in elastomers - Theology and thixotropy control of liquid systems - Used as anti-settling, thickening, anti-sagging agent - Improvement of free flow and anti-caking - Characteristics of powders - High transparency
