Product name: Hydrophobic Fumed silica Basisil-702
Packing: 10kg/bag, 200kg/pallet
Brand: Basisil
Basisil-702 is hydrophobic fumed silica after treated with Silicone Oil based on a hydrophilic fumed silica with a specific surface area of 200 m2/g. It’s a kind of high purity white colloidal powder. Packing 10kg/bag.
It is a countertype to Aerosil R202 from Evonik
Application:
RTV silicone sealants, especially electronic potting
sealants and Silicone rubber;
Coatings, inks, paint
Defoamer, etc.
Thixotropy and reinforcement in RTV silicone sealants, the hydrophobic feature given RTV silicone sealants a long periods Shelf-life.
Rheology control in adhesives.
Low thickening effect and excellent processability
enable high loading in polymers
Improve the free flow of powder coatings and anti- caking.
