Dow Corning OFS-6778 is a methyl siliconate-based coupling agent that enhances adhesion and reduces viscosity in waterproof/anti-corrosion coatings. Its reactive siloxane bonds form hydrophobic layers, improving wet adhesion (>90% retention) and mechanical strength in composites. Ideal for concrete/metal substrates, it complies with REACH/RoHS and offers low VOC (<50 g/L), making it suitable for commercial buildings, bridges, and industrial coatings
Deep Penetration - Small molecular structure ensures thorough substrate infiltration for durable waterproofing
Interfacial Bonding - Siloxane crosslinks bridge organic resins (epoxy, acrylic) and inorganic substrates (concrete, metals)
Process Efficiency - Lowers viscosity (40% aqueous solution, dilutable to 3%) for easy application
Multi-Substrate Compatibility - Effective on concrete, metals, and polyolefins
Infrastructure Protection - Waterproofing for bridges/highways with >1,000-hour salt spray resistance
Metal Anti-Corrosion - Aluminum/steel coatings with extended service life
Polymer Composites - Mineral filler modification for improved dispersibility in polyolefin
