Dow Corning OFS-6341 Hydrophobic Silane Coupling Agent

Dow Corning OFS-6341 (N-octyltriethoxysilane) is a hydrophobic silane coupling agent that enhances adhesion and water resistance in coatings and composites. Its small molecular structure enables deep penetration into concrete and metal substrates, forming durable siloxane crosslinks. Ideal for waterproofing and anti-corrosion applications, it improves mechanical strength (>90% wet adhesion retention) and complies with REACH/RoHS, reducing VOC emissions by 15–20%

Features Of Dow Corning OFS-6341 Hydrophobic Silane Coupling Agent

  1. Deep Penetration - Small molecule design ensures thorough substrate infiltration for long-lasting hydrophobicity .

  2. Interfacial Bonding - Ethoxy groups react with inorganic surfaces; alkyl chains enhance compatibility with polymers .

  3. Process Efficiency - Low viscosity (0.875 g/cm³) facilitates uniform dispersion in formulations .

  4. Multi-Substrate Compatibility - Effective on concrete, metals, and polyolefins

Typical Applications Of Dow Corning OFS-6341 Hydrophobic Silane Coupling Agent

  1. Concrete Waterproofing - Commercial buildings and bridges with >1,000-hour salt spray resistance

  2. Anti-Corrosion Coatings - Aluminum/steel protection in harsh environments

  3. Polymer Composites - Mineral filler modification for improved dispersibility in polyolefins .

  4. Infrastructure Sealants - Parking garages and highways with extended service life
