SILRES BS 375

SILRES®BS 375 is a solvent dilutable concentrate of Alkylsilane/siloxane. In diluted form with organic solvent, it serves as a water-repellent for impregnating mineral building materials and as a primer for mineral substrates. It develops its water-repellent effect by reacting with atmospheric humidity and with water absorbed on the walls of the pores and capillaries of the building material. SILRES®BS 375 penetrates the building material further and exhibits higher resistance to alkalis, than pure methyl silicone resins.
