Thermo Scientific™ 3-(Trimethoxysilyl)propyl methacrylate ≥97%

3-(Trimethoxysilyl)propyl methacrylate (TMSPMA) is a silane coupling agent commonly used to improve the adhesion between organic polymers and inorganic materials such as glass, metals, and ceramics. It contains both a methacrylate group for copolymerization with vinyl monomers and a trimethoxysilyl group capable of bonding with hydroxylated surfaces, making it a highly versatile reagent in surface modification, composite manufacturing, and adhesive formulation.

With a purity of ≥97%, TMSPMA is supplied as a reactive liquid and should be handled under dry conditions to avoid premature hydrolysis. It is widely used in coatings, sol-gel processes, silica surface functionalization, and dental materials.

Key Features

• High purity: ≥97% (titration with NaOH)
• Dual-functionality for organic–inorganic bonding
• Enhances adhesion, dispersion, and durability in composite materials
• Compatible with polyesters, acrylics, epoxies, and urethanes
• Ideal for sol-gel chemistry and coupling applications
• GHS07 classified (Irritant) – handle with appropriate PPE
• Stable under ambient storage conditions

Applications

• Glass fiber treatment in reinforced plastics
• Surface modification of silica, alumina, and titania
• Adhesion promoter in sealants, coatings, and adhesives
• Functional silane for sol-gel formulations and hybrid materials
• Used in dental resins, optical coatings, and electronics packaging
• Coupling agent in polymer nanocomposites and biomedical devices
