Description

Dibutylchloroethenylsilane is a versatile organosilicon compound characterized by its reactive chloro and ethenyl (vinyl) functional groups. This dual functionality makes it a valuable intermediate for introducing silicon-containing moieties into polymer backbones and organic molecules. It is essential for manufacturers in the silicone, specialty polymer, and advanced materials sectors seeking to modify surface properties, enhance adhesion, or create cross-linked networks. The compound Dibutylchloroethenylsilane CAS NO 62238-35-1 is a key building block for synthesizing tailored silanes and silicone-based hybrids.

Application

• Silicone Polymer Modification: Acts as a reactive monomer or cross-linking agent in the synthesis of specialty silicone resins and elastomers.
• Surface Treatment & Coupling Agent: Used to functionalize inorganic surfaces like glass, silica, and metals to improve the adhesion of organic polymers and coatings.
• Organic Synthesis Intermediate: Serves as a precursor in hydrofunctionalization and other reactions to create novel organosilicon compounds for research and development.
• Adhesive & Sealant Formulations: Incorporated to enhance moisture-cure properties, adhesion promotion, and durability in high-performance sealants and adhesives.
• Release Coatings & Molding Agents: Utilized in the production of silicone-based release liners and as a component in mold-making materials.
• Hybrid Material Fabrication: Enables the creation of organic-inorganic hybrid (OIH) materials with customized mechanical and thermal properties.

Quality Control

Our Dibutylchloroethenylsilane is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including assay and impurity profiling by GC and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with each shipment to guarantee compliance with your technical requirements.

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). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; keep the container tightly sealed under an inert atmosphere such as nitrogen or argon to prevent degradation. Isolate from incompatible materials.
