Description

3-Methacryloxypropyldimethylethoxysilane is a bifunctional organosilane coupling agent featuring both a methacrylate group and a hydrolyzable ethoxysilyl group. This dual functionality makes it a critical component for enhancing the adhesion and compatibility between inorganic materials and organic polymer matrices. It is essential for manufacturers in the composites, coatings, adhesives, and sealants industries seeking to improve the mechanical properties and durability of their products. The compound is supplied under strict quality control to ensure consistent performance in demanding applications.

Application

• As a coupling agent in fiberglass-reinforced plastics (FRP) and mineral-filled composites to improve interfacial bonding and mechanical strength.
• A key surface modifier for silica, glass, and other inorganic fillers to enhance their dispersion and compatibility in polymer systems like acrylics and polyolefins.
• Used in the formulation of adhesives and sealants to promote adhesion to glass, metal, and mineral substrates.
• As a crosslinking agent or co-monomer in moisture-curable silicone-modified acrylic resins and coatings.
• Employed in the production of dental composites and restorative materials to bond filler particles to the resin matrix.
• For the surface treatment of nanoparticles to prevent agglomeration and enable their use in advanced nanocomposites.

Quality Control

Our production of 3-Methacryloxypropyldimethylethoxysilane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, purity verification, and impurity profiling, to ensure it meets precise specifications for industrial and advanced material applications. A Certificate of Analysis (COA) detailing all relevant parameters is provided with each shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed after initial use to prevent degradation by atmospheric moisture. Keep away from heat, sparks, and open flame.
