Description

Dichlorovinylsilane is a highly reactive organosilicon compound, serving as a critical building block in the synthesis of advanced silicone polymers and functional materials. Its core value lies in the vinyl group, which enables cross-linking and polymerization, and the chlorosilane functionality, which facilitates further chemical modification. This makes it an essential precursor for manufacturers in the silicone rubber, specialty coatings, and adhesives industries seeking to enhance product durability and performance.

Application

• Silicone Polymer Synthesis: A key monomer for producing vinyl-functional silicone fluids, resins, and high-consistency rubber (HCR).
• Cross-linking Agent: Imparts vinyl groups into silicone networks for peroxide-cured or platinum-catalyzed addition cure systems.
• Surface Modification: Used as a coupling agent or surface treatment for minerals, glass, and fillers to improve compatibility with organic matrices.
• Intermediate for Silane Coupling Agents: Serves as a starting material for synthesizing vinyltrialkoxysilanes and other functional silanes.
• Specialty Coatings & Adhesives: Incorporated into formulations to enhance adhesion, weather resistance, and thermal stability.
• Pharmaceutical & Electronic Intermediates: Used in the controlled synthesis of specific organosilicon compounds for advanced applications.

Quality Control

Our Dichlorovinylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets exacting industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your production processes.

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 highly volatile and hygroscopic (moisture-sensitive) nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) and handle in a dry environment to prevent hydrolysis. Keep away from strong bases, oxidizers, and water.
