DOWSIL OFS-6032 Silicate Coupling Agent

DOWSIL OFS-6032 (vinylbenzylamino-functional silane) Silicate Coupling Agent enhances adhesion between organic resins (epoxy, polyester) and inorganic substrates (glass, metals) via dual-reactive groups. Its 40% active content in methanol improves wet/dry tensile strength (>30% increase) and resin wettability. Compliant with REACH/RoHS, it serves as a coupling agent or additive (0.05–1.0% dosage) for FRP, cables, and coatings, with stable pre-hydrolysis solutions (0.1–0.5% active) for glass fiber treatment

Features Of DOWSIL OFS-6032 Silicate Coupling Agent

  1. Dual Reactivity - Vinylbenzylamine bonds with polymers; methoxy groups link to inorganic fillers

  2. Process Adaptability - Self-emulsifying in water (forms stable 0.1–0.5% solutions) or soluble in alcohols

  3. Performance Boost - Enhances flexural strength in composites (e.g., polypropylene-mica systems)

Typical Applications Of DOWSIL OFS-6032 Silicate Coupling Agent

  1. FRP Composites - Glass fiber sizing for automotive/construction

  2. Cable Insulation - Clay-filled EPDM dielectric enhancement

  3. Thermoplastics - Mineral-filled PP/PC compatibility improvement
