SILRES BS 375

CAS number

  • 63148-57-2

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.
