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. By reducing the amount of water entering the substrate, Protectosil® CHEM-TRETE® BSM 400 reduces the intrusion of waterborne contaminants such as acid rain, salt and dirt, and reduces the deteriorating effects of these contaminants, including spalling, scaling, efflorescence, leaching and staining.
Typical Applications
Benefits at a glance
The main benefits of the product are:
• High resistance to wind-driven rain
• Excellent resistance to chloride ion ingress
• Reduced efflorescence
• Breathable system
• Deep penetration into substrate
• No change in surface appearance
• Will not leave a residue on nonporous substrates, (e.g. glass) so no masking required
• High resistance to alkali attack
• Long service life
• Substrates already treated with Protectosil® CHEM-TRETE® BSM 400 can be painted over
• Keeps substrates cleaner
