Protectosil® CHEM-TRETE® BSM 400

Clear, 100% silane water repellent.

PRODUCT OVERVIEW:

Protectosil® CHEM-TRETE® BSM 400 brings you the next generation in silane technology. Our chemists have developed a pure silane that yields a water repellent with the longest service life available, unsurpassed performance on brick masonry and the lowest possible levels of volatile organic compounds. Protectosil® CHEM-TRETE® BSM 400 can be applied in the most extreme temperature conditions without changing the surface appearance of the substrate. By penetrating the surface and creating a chemical bond, Protectosil® CHEM-TRETE® BSM 400 permanently attaches to the substrate.

APPLICATIONS:

For use on brick masonry, to protect against the ingress of wind-driven rain. For use on vertical concrete structures, to protect the reinforcing steel from corrosion due to the effects of water and other waterborne contaminants. Reduces the effects of mildew, efflorescence, and stains on vertical concrete and masonry buildings. Imparts water repellency to a substrate for an extended time. Provides resistance against acid rain, alkali attack and other atmospheric pollutants.
