Description

Trivinylchlorosilane is a highly reactive organosilicon compound, specifically a chlorosilane with three vinyl functional groups. This unique structure makes it a critical cross-linking agent and precursor in advanced material synthesis, offering exceptional versatility in modifying polymer backbones and inorganic surfaces. It is essential for manufacturers in the silicone elastomer, specialty polymer, and surface treatment industries seeking to introduce durable, reactive vinyl functionalities into their products.

Application

• Cross-linking Agent for Silicone Polymers: A key component in peroxide-cure silicone rubber formulations (HVCR), providing excellent heat resistance and mechanical properties.
• Surface Modification & Coupling Agent: Used to functionalize silica, glass, and other inorganic fillers to improve compatibility and bonding with organic polymer matrices.
• Synthesis of Specialty Silanes: Serves as a versatile intermediate for producing other functionalized vinylsilanes and siloxanes.
• Adhesive and Sealant Formulations: Enhances the adhesion and cross-linking density in high-performance industrial adhesives and sealants.
• Release Coatings and Molding: Employed in the production of release liners and for creating mold-making materials with specific surface properties.
• Photoresist and Electronic Materials: Investigated for use in lithography and as a precursor for low-k dielectric materials in microelectronics.

Quality Control

Our Trivinylchlorosilane is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including Gas Chromatography (GC) and titration methods, to confirm identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and ignition sources. Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Incompatible with strong acids, bases, and oxidizing agents.
