Silane - Siloxanes

SILRES® BS 280 is a solvent-free silicone concentrate based on
silane/siloxane that is dilutable with organic solvents. Diluted solutions of SILRES® BS 280 are highquality water repellents for
impregnating mineral building materials, especially silicate free natural stones like limestone or gypsum. SILRES® BS 280 develops its waterrepellent effect after application to
construction materials as a result of a reaction with atmospheric humidity.
