SILRES® BS 6920

SILRES® BS 6920 by Wacker is an alpha-silane-terminated polyether that cures on contact with moisture. Its chemical structure has been optimized to achieve low viscosity. Its low viscosity makes solvent-free processing possible, although a solvent may be added if required. Exhibits high flash point, so no special precautions need be taken. It provides flooring with excellent stain protection and has a color-intensifying effect. SILRES® BS 6920 can be processed into ready-to-use impregnating agents and thin coatings for concrete and flowing-screed floors. To accelerate curing, it is usually formulated with an amino-functional silane that also ensures good adhesion to cement-bound substrates.
