SILRES® BS 16

Siliconates

SILRES® BS 16 is an aqueous solution of potassium methyl siliconate and
is used in diluted form for the impregnation of mineral construction materials to make them water-repellent.
SILRES® BS 16 develops its water-repellent properties by reaction with
atmospheric carbon dioxide (CO2). The active substance formed from the silicone masonry water repellent is polymethylsilicic acid.
As with all siliconates, however, SILRES® BS 16 can cause a white
deposit on the surface of colored construction materials, or if used outside the application guidelines.
