Description

3-Methacryloxypropyltris(Methoxyethoxy)Silane is a high-purity, multi-functional organosilane coupling agent. This compound is engineered to create strong, durable bonds between inorganic substrates and organic polymer matrices, significantly enhancing composite material performance. It is essential for manufacturers in the coatings, adhesives, sealants, and advanced composites industries seeking to improve adhesion, mechanical strength, and environmental resistance in their products.

Application

• As a key adhesion promoter in acrylic-based paints, coatings, and primers for metals, glass, and plastics.
• To enhance the bonding and dispersion of inorganic fillers (e.g., silica, glass fibers) in methacrylate resin composites and dental restorative materials.
• As a surface modifying agent for nanoparticles and minerals to improve compatibility with organic polymer systems.
• In the formulation of moisture-curable sealants and adhesives to ensure long-term durability and water resistance.
• For the surface treatment of glass fibers to improve interfacial adhesion in fiber-reinforced plastics (FRP).
• As a crosslinking agent or co-monomer in specialty silicone-modified acrylic polymers.

Quality Control

Our production of 3-Methacryloxypropyltris(Methoxyethoxy)Silane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay (GC/HPLC), identity confirmation (IR, NMR), and purity checks for key impurities. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your specific application 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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from heat and open flame.
