Description

Dichloromethylvinylsilane is a highly reactive organosilicon monomer characterized by its vinyl and chloromethyl functional groups. This compound is a critical building block in the synthesis of specialized silicone polymers and serves as a versatile intermediate for introducing reactive sites into organic and inorganic matrices. It is essential for manufacturers in the silicone, advanced materials, and specialty chemical sectors seeking to develop products with tailored surface properties, adhesion, and cross-linking capabilities.

Application

• Silicone Polymer Synthesis: A key monomer for producing vinyl-functional silicone fluids, resins, and elastomers.
• Surface Modification & Coupling Agent: Used to functionalize inorganic surfaces like glass, silica, and metals to improve adhesion and compatibility with organic polymers.
• Cross-linking Agent: Imparts reactive sites for curing and cross-linking in silicone rubber and sealant formulations.
• Intermediate for Specialty Silanes: Serves as a precursor for synthesizing other functional silanes, such as those with amino or epoxy groups.
• Adhesion Promoter: Enhances the bond strength in coatings, adhesives, and composite materials.
• Hydrophobic Coatings: Used in formulations to create water-repellent surfaces on textiles, construction materials, and electronics.

Quality Control

Our Dichloromethylvinylsilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity. Recommended storage temperature is 2-8°C.
