Description

Triisobutoxyvinylsilane is a highly reactive organosilicon compound, specifically a vinyl-functional alkoxysilane. Its unique molecular structure, featuring both hydrolyzable isobutoxy groups and a polymerizable vinyl group, makes it a critical coupling agent and monomer for advanced material synthesis. This chemical is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance material properties like adhesion, cross-linking density, and surface modification.

Application

• Cross-linking Agent: Used as a co-monomer in the production of moisture-curable polymers, silicone resins, and cross-linked polyethylene, improving thermal stability and mechanical strength.
• Surface Modification & Coupling Agent: Imparts reactive vinyl groups to inorganic surfaces like glass, silica, and metals, promoting adhesion between organic polymers and inorganic substrates in composite materials.
• Silicone Intermediate: Serves as a key precursor in the synthesis of specialized silicone fluids, elastomers, and resins with tailored properties.
• Adhesive & Sealant Formulations: Enhances the adhesion, flexibility, and durability of high-performance silicone and hybrid polymer-based adhesives and sealants.
• Filler Treatment: Used to modify mineral fillers (e.g., clay, calcium carbonate) and reinforcements (e.g., fiberglass) to improve their compatibility and dispersion in plastic and rubber compounds.
• Release Coatings: A component in the formulation of silicone-based release coatings for papers and films.
• Water Repellents: Employed in the manufacture of water-repellent treatments for textiles, stone, and construction materials.
• Research & Development: Utilized in laboratories for developing novel organosilicon compounds, dendrimers, and functional materials.

Quality Control

Our Triisobutoxyvinylsilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and NMR to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, specific gravity, refractive index, and other critical parameters is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under a dry, inert atmosphere (e.g., nitrogen) after each use to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
