Description

Chloroethenylethylmethyl-Silane is a specialized organosilicon compound featuring a reactive chloro and vinyl group on the silicon center. This unique bifunctional structure makes it a valuable intermediate for introducing silicon-based functionality into polymers and surfaces. It is particularly sought after by manufacturers in the advanced materials and specialty chemical sectors for developing silicone-based products with tailored properties. Key applications include its use as a coupling agent, surface modifier, and a monomer for synthesizing custom siloxane polymers.

Application

• Silicone Polymer Synthesis: Serves as a key monomer or cross-linking agent in the production of specialty silicone resins, elastomers, and fluids with specific mechanical and thermal properties.
• Surface Modification & Coupling Agent: Used to treat inorganic fillers (e.g., silica, glass) to improve their compatibility and dispersion in organic polymer matrices like rubbers and plastics.
• Adhesive & Sealant Formulations: Functions as an adhesion promoter and moisture-cure component in high-performance silicone-based adhesive and sealant systems.
• Release Coatings: Employed in the formulation of silicone release liners for pressure-sensitive labels and tapes.
• Hybrid Material Fabrication: Acts as a precursor in sol-gel processes to create organic-inorganic hybrid coatings with enhanced durability and functionality.
• Pharmaceutical & Agro-Intermediate: Utilized as a building block in the synthesis of more complex organosilicon molecules for pharmaceutical and agrochemical applications.

Quality Control

Our Chloroethenylethylmethyl-Silane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including Gas Chromatography (GC) and NMR spectroscopy, to verify identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications 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, and well-ventilated area at room temperature (15-25°C). Due to its highly volatile and hygroscopic nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
