Description

2-(Trimethoxysilyl)Ethylacrylate is a bifunctional organosilane monomer featuring both a polymerizable acrylate group and hydrolyzable methoxysilyl groups. This dual functionality makes it a critical coupling agent and adhesion promoter, enabling strong bonds between organic polymers and inorganic substrates. It is essential for manufacturers in the coatings, adhesives, sealants, and composites industries seeking to enhance durability, weather resistance, and mechanical performance in their final products.

Application

• Crosslinking Agent in moisture-curable silicone-modified acrylic resins and sealants.
• Adhesion Promoter for coatings and inks on glass, metal, and mineral surfaces.
• Surface Modifier for silica, glass fibers, and other fillers to improve compatibility in polymer composites.
• Dental & Medical Materials as a key monomer in resin-based composites and bonding agents.
• Fiber Treatment to enhance the interfacial strength between reinforcing fibers and polymer matrices.
• UV-Curable Systems for rapid-cure coatings and 3D printing resins requiring improved substrate adhesion.

Quality Control

Our production of 2-(Trimethoxysilyl)Ethylacrylate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure consistency and performance. Certificates of Analysis (COA) detailing all critical parameters are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis and polymerization.
