Description

Dichloro(Methyl)Phenoxysilane is a versatile organosilicon compound primarily used as a key intermediate in the synthesis of silicone polymers and functional silanes. Its value lies in its reactive chlorosilane and phenoxy groups, which allow for controlled modification of material surfaces and polymer backbones. This chemical is essential for manufacturers in the silicone resins, adhesives, and specialty coatings industries, as well as for research and development of novel hybrid organic-inorganic materials.

Application

• Silicone Resin Precursor: A critical building block for manufacturing heat-resistant and weatherable silicone resins used in protective coatings and electrical insulation.
• Surface Modification Agent: Used to functionalize inorganic surfaces like silica, glass, or metals, improving adhesion and compatibility in composite materials.
• Coupling Agent Synthesis: Serves as an intermediate in the production of specialized silane coupling agents for the plastics and rubber industries.
• Adhesive & Sealant Formulations: Imparts specific reactivity and stability properties in high-performance silicone-based adhesives and sealants.
• Pharmaceutical & Agro-chemical Intermediates: Employed in the synthesis of more complex organosilicon molecules for specialized applications.
• Research & Development: Used in laboratories for developing new silicone-based materials with tailored properties.

Quality Control

Our Dichloro(Methyl)Phenoxysilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and high purity, meeting the specifications required for industrial and research applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your quality standards.

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 hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from strong bases, oxidizers, and sources of ignition.
