Description

Tri(Isopropoxy)Vinylsilane is a versatile organosilicon compound, specifically a vinyl-functional trialkoxysilane, that serves as a critical coupling agent and surface modifier. Its value lies in its dual functionality, featuring a hydrolyzable isopropoxy group for inorganic material bonding and a polymerizable vinyl group for organic matrix integration. This product is essential for manufacturers in the coatings, adhesives, and advanced composite materials industries seeking to enhance interfacial adhesion and material performance.

Application

• Crosslinking Agent & Adhesion Promoter: Used in silicone-based sealants, adhesives, and RTV (Room Temperature Vulcanizing) rubbers to improve adhesion to various substrates.
• Surface Treatment for Fillers & Minerals: Modifies the surface of silica, glass fibers, and other minerals to improve compatibility and dispersion in polymer matrices like polyethylene and polypropylene.
• Precursor for Silicone Resins & Polymers: Acts as a monomer in the synthesis of specialty silicone resins, contributing heat resistance and weatherability to protective coatings.
• Fabric & Fiber Treatment: Imparts water repellency, stain resistance, and improved handle to textiles and non-woven materials.
• Coupling Agent in Mineral-Filled Composites: Enhances mechanical properties and moisture resistance in composite materials used in automotive and construction.
• Intermediate for Further Chemical Synthesis: Serves as a building block for creating more complex organosilane derivatives with tailored properties.

Quality Control

Our Tri(Isopropoxy)Vinylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications for industrial and R&D applications. A Certificate of Analysis (COA) detailing all test results is provided with every 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 highly volatile nature, containers must be kept tightly sealed after opening to minimize moisture absorption and evaporation. Keep away from heat, sparks, and open flame.
