| Product Description: A clear, penetrating, breathable VOC-compliant surface treatment for use on concrete. The Isobutylakoxy functional silane allows for faster dry times and superior performance on high quality mix designs typical of new bridge decks. Creates a deep hydrophobic layer that prevents water and waterborne contaminants from entering the substrate and causing premature deterioration. By combining ultra-low surface tension with a tailored rate of reaction, Protectosil 300S 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—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, precast, GFRC and high-strength concrete, to protect the reinforcing steel from corrosion due to the effects of water, deicing salts another waterborne contaminates. 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 concentrations (piers, coastal buildings), to provide a high-performance, long-lasting chloride screen. Advantages: PROTECTOSIL 300s IS SOLVENT-FREE, Isobutylalkoxysilane. Protectosil 300S penetrates deeper than traditional silane and siloxane solvent-or water-carried systems. This deeper penetration gives a long-lasting, resistance against water and chloride intrusion. Protectosil 300S’s breathable system greatly reduces the amount of water that enters a substrate, thus promoting a “drying out” of the substrate. Reduces the deteriorating effects of water, such as alkali silica reactivity. By incorporating Protectosil 300S into your integrated design, you can earn vital Leadership in Energy & Environmental Design (LEDD) credits for both new and existing construction projects. The main benefits of the product are: - Excellent resistance to chloride ion ingress
