Protectosil® CHEM TRETE BSM 400

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

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.

Benefits at a glance

Protectosil® CHEM-TRETE® BSM 400 is composed of pure isobutyltrialkoxysilane. Protectosil® CHEM-TRETE® BSM 400 is designed to penetrate deep into the substrate and impart a high level of water and chloride ion screening. This provides the substrate with long-lasting protection. Because of the purity of Protectosil® CHEM-TRETE® BSM 400, it will not leave a residue on nonporous substrates such as clean glass windows, metal frames or painted surfaces. Protectosil® CHEM-TRETE® BSM 400 complies with most state and federal volatile organic content regulations. In addition, Protectosil® CHEM-TRETE® BSM 400 does not contain exempt solvents (such as 1,1,1 trichloroethane) that may be hazardous. For the proper VOC regulations in your specific location, contact your Protectosil® representative or reference our brochure on VOC regulations, which is available https://silanes.evonik.com/en. The Protectosil® product line has an unprecedented track record in protecting brick masonry, concrete and natural stone structures from deterioration due to water and waterborne contaminants. Structures treated in the 1970s are still protected, and these results are documented by state, federal and private agencies. By incorporating Protectosil® CHEM-TRETE® BSM 400 into your integrated design, you can earn vital Leadership in Energy & Environmental Design (LEED) credits for both new and existing construction projects.
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
