| Product Description: A clear penetrating breathable VOC compliant surface treatment for use on concrete. The unique 100% silane treatment(no solvent) penetrates into the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. Creates a deep hydrophobic layer which prevents water and waterborne contaminants from entering the substrate and causing premature deterioration. By combining a low surface tension with a tailored rate of reaction, Protectosil BHN is able to move through the moisture boundary layer that lines the pore structure of the substrate. This permits the development of uniform gradient permeation or a consistent level of protection throughout the entire depth of penetration – allowing for longer treatment life, especially on wearing surfaces. Applications: For use on cast-in-place, recast, GFRC and high-strength concrete, to protect the reinforcing steel from corrosion due to the effects of water, deicing salts and other waterborne contaminants. Alleviates deterioration of concrete due to alkali-silica reactivity. For use on bridge decks where fast drying is needed to minimize lane closures. For treating heavy-traffic wearing surfaces or areas that receive high salt concentration (piers, costal buildings), to provide a high-performance, long-lasting chloride screen. Advantages: Protectosil BHN is a solvent-free, 100% alkyltralkoxysilane. Protectosil BHN penetrates deeper than traditional silane and siloxane solvent- or water-carried system. This deeper penetration gives a long lasting, resistance against water and chloride intrusion. Protectosil BHN’s breathable system greatly reduces the amount of water that enters a substrate, thus promoting a “drying out” of the substrate. Reduces the deteriorating effect of water, such as alkali silica reactivity. By incorporating Protectosil BHN 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: - Excellent resistance to chloride ion ingress

- Mitigation of AAR & ASR deterioration
- Deep penetration into substrate
- No change in surface appearance
- High resistance to alkali attack
- Long service life
