3-Methacryloxypropyltrimethoxysilane is a methacrylate-functional organosilane coupling agent that combines an organic reactive methacryloxy group with hydrolyzable trimethoxy groups. This dual functionality enables strong chemical bonding between organic polymers and inorganic substrates such as glass, metal, and mineral fillers.
It enhances adhesion, mechanical strength, and moisture resistance in thermosetting resins, thermoplastics, and composites. It is widely used as an adhesion promoter, surface modifier, and coupling agent in coatings, adhesives, sealants, and fiberglass-reinforced plastics.
Key Features:
Improves adhesion between organic and inorganic materials
Enhances moisture, weather, and chemical resistance
Provides excellent coupling in filled and reinforced systems
Compatible with acrylic, polyester, and epoxy resins
Applications:
Fiber-reinforced plastics and composites
Adhesives, sealants, and coatings
Glass fiber sizing and surface treatments
Mineral-filled thermosetting and thermoplastic systems
CAS # 2530-85-0
