3-Acryloyloxypropyltrimethoxysilane

Product Overview

3-Acryloyloxypropyltrimethoxysilane is a highly reactive organosilane coupling agent designed to bridge the interface between inorganic substrates and organic polymers. This advanced chemical features an acryloxy functional group that readily copolymerizes with thermosetting and thermoplastic resins, while the trimethoxysilane moiety hydrolyzes to form stable bonds with glass, minerals, and metals. It is extensively utilized in high-performance composite materials, wire and cable insulation, and protective coatings where superior adhesion and durability are critical.

Key Specifications

Industrial Applications

In the unsaturated polyester composite industry, this coupling agent significantly enhances mechanical strength, electrical insulation, and light transmission properties. It is particularly effective in improving wet performance, ensuring that glass fiber reinforced materials maintain integrity under humid conditions. When glass fibers are treated with this agent, the wet mechanical strength and electrical properties of the resulting composite are markedly improved.

The wire and cable industry utilizes this product to treat EPDM systems filled with peroxide cross-linked compounds. This application leads to improved consumption factors, specific inductance, and capacitive reactance, ensuring reliable performance in demanding electrical environments. Additionally, when copolymerized with vinyl acetate and acrylic or methacrylic monomers, the resulting polymers are widely adopted in coatings, adhesives, and sealants.

Performance Advantages

• Superior reactivity compared to conventional methacryloxysilanes.
• Enhances adhesion between organic polymers and inorganic fillers.
• Improves wet electrical properties and mechanical strength.
• Provides excellent durability and weather resistance in coatings.
• Compatible with major industry standards such as DOWSIL Z-6530 and Shin-Etsu KBM-5103.

Storage and Handling

To maintain optimal quality, store in the original unopened container at temperatures of 25℃ or below. The shelf life is one year from the production date when stored correctly. Expired products should only be used after passing rigorous quality testing. Packaging options include 25Kg plastic drums, 200Kg drums, or 1000Kg IBC containers to suit various industrial scale requirements. Always follow standard safety protocols for Class 8 dangerous goods during transport and handling.
