Product name: Hydrophobic Fumed silica Basisil-714
Packing: 10kg/bag, 200kg/pallet
Brand: Basisil
Basisil-714 is a hydrophobic fumed silica after treated with DDS (Dimethyldichlorosilane) based on a hydrophilic fumed silica with a specific surface area of 200 m2/g.
It is a countertype to Aerosil R974 from Evonik
Application:
Silicone rubber and silicone sealants
Paints and coatings
Negative toner
Adhesives
Coating polymers
Cosmetics
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.
Water resistant, for thickening and hydrophobising of liquid systems.
