Dow Corning OFS-6032 Gamma-Methacryloxypropyltrimethoxysilane

Dow Corning OFS-6032 Gamma-Methacryloxypropyltrimethoxysilane is a bifunctional silane coupling agent from the OFS series, featuring methacrylate and trimethoxysilyl groups. It enhances adhesion between organic polymers and inorganic substrates like glass, metals, or fillers—especially in UV-curable coatings, adhesives, and composite materials requiring durable interfacial bonding and hydrolytic stability.

Features Of Dow Corning OFS-6032 Gamma-Methacryloxypropyltrimethoxysilane

  1. Bifunctional silane coupling agent with methacrylate group for covalent bonding to acrylic, polyester, and epoxy resins.

  2. Three hydrolyzable methoxy groups provide rapid and robust condensation with metal oxides, glass, and mineral fillers.

  3. Enables enhanced interfacial adhesion in radiation-curable (UV/EB) composite systems without compromising cure speed.

  4. Low volatility and high hydrolytic stability in anhydrous formulations extend shelf life and processing window.

  5. Compatible with free-radical polymerization chemistries—no inhibition of photoinitiator activity under standard curing conditions.

Typical Applications Of Dow Corning OFS-6032 Gamma-Methacryloxypropyltrimethoxysilane

  1. Adhesion promoters in UV-curable coatings for aluminum, stainless steel, and glass substrates.

  2. Surface modifier for silica and glass microspheres in high-performance composites and optical adhesives.

  3. Functional additive in dental restorative resins to improve filler–matrix bonding and mechanical durability.

  4. Interfacial enhancer in fiber-reinforced plastics (FRP) using E-glass or basalt fibers with acrylate-based matrices.

  5. Key ingredient in scratch-resistant hardcoats for polycarbonate and PMMA optical lenses.
