Dow Corning OFS-6124 Silane Coupling Agent

Dow Corning OFS-6124 (phenyltrimethoxysilane) is an epoxy-functional silane coupling agent that enhances adhesion between resins (epoxy, UV-curable) and inorganic substrates (metals, glass fibers). It forms siloxane crosslinks via hydrolysis, improving wet adhesion (>90% retention), mechanical strength, and chemical resistance in composites. Ideal for coatings and adhesives, it enables fast curing at ambient temperatures and complies with REACH/RoHS, reducing VOC emissions by 15–20%

Features Of Dow Corning OFS-6124 Silane Coupling Agent

  1. Interfacial Reinforcement - Epoxy groups bond with resins; methoxy links to metals/fillers, optimizing stress transfer .

  2. Process Efficiency - Lowers viscosity (1.062 g/cm³) for homogeneous filler dispersion .

  3. Durability - Enhances UV/aging resistance in coatings (salt spray resistance >1,000 hours)

  4. High-Temperature Stability - Maintains performance up to 233°C, suitable for polyolefin modifications

Typical Applications Of Dow Corning OFS-6124 Silane Coupling Agent

  1. Architectural Coatings - Waterproofing concrete in commercial buildings

  2. Automotive Adhesives - Metal bonding with improved corrosion resistance .

  3. Electronic Encapsulation - Epoxy-based sealants for moisture protection

  4. Polymer Composites - Mineral filler modification for enhanced dispersibility .
