| A clear, penetrating, breathable water repellent for use on exterior above-grade concrete masonry units and some natural stones. Penetrates the surface and bonds chemically to the substrate, resulting in permanent attachment of the water repellent molecule. Protectosil CHEM-TRETE 40 VOC is not a coating and as a result will not discolor change the surface appearance in anyway. By reducing the amount of water that enters 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 rebar corrosion, spalling scaling, efflorescence, leaching and staining. 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 staining on vertical concrete and masonry buildings. Imparts water repellency to a substrate for an extended time Advantages: 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. Because of 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. In addition, Protectosil CHEM-TRETE 40 VOC does not contain exempt solvents (such as 1,1,1 trichloroethane) that may be hazardous. The Protectosil CHEM-TRETE 40 VOC product line has an good 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 document by state, federal and private agencies. By incorporating Protectosil CHEM-TRETE 40 D into your integrated design, you can earn vital Leadership and 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
