Protectosil® CHEM TRETE 40 VOC

Protectosil® CHEM-TRETE® 40 VOC is a clear, penetrating, breathable water repellent for use on exterior above-grade concrete, brick masonry, concrete masonry units and some natural stones. This product penetrates the surface to chemically bond to the substrate, resulting in a permanent attachment of the water repellent molecule. Protectosil® CHEM-TRETE® 40 VOC is not a coating and as a result will not discolor or change the surface appearance in any way. By reducing the amount of water entering the substrate, Protectosil® CHEM-TRETE® 40 VOC reduces the intrusion of waterborne contaminants such as salt and dirt, and reduces the deteriorating effects of these contaminants, such as rebar corrosion, spalling, scaling, efflorescence, leaching and staining.

Typical Applications

For use on concrete, to protect the reinforcing steel from corrosion due to the effects of water, deicing salts and other waterborne chemicals. For use on brick masonry, to protect against the ingress of wind-driven rain. For use on concrete pavement for highways, parking decks and airport runways, to reduce scaling due to deicer chemicals. Reduces the effects of mildew, efflorescence and stains on vertical concrete and masonry buildings. Imparts water repellency to a substrate for an extended time.

Benefits at a glance

Protectosil® CHEM-TRETE® 40 VOC is an isobutyltrialkoxysilane in an alcohol carrier. The silane 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. Due to the purity of Protectosil® CHEM-TRETE® 40 VOC, it will not leave a residue on nonporous substrates such as glass windows, metal frames and painted surfaces. Protectosil® CHEM-TRETE® 40 VOC meets the volatile organic content regulations in numerous states. It 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. The Protectosil® CHEM-TRETE® 40 VOC product line has an unprecedented track record in protecting concrete, masonry 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. Byincorporating Protectosil® CHEM-TRETE® 40 VOC into your integrated design, you can earn vital Leadership in Energy & Environmental Design (LEED) credits for both new and existing construction projects.
