Description

Dichloro(Ethoxy)Phenylsilane is a versatile organosilicon compound that serves as a key intermediate in advanced material synthesis. Its bifunctional chlorosilane and alkoxysilane groups make it a valuable precursor for introducing phenylsilane moieties into polymers and surfaces. This chemical is essential for manufacturers in the silicone resins, adhesives, and specialty coatings industries seeking to enhance thermal stability and adhesion properties.

Application

• Silicone Resin & Polymer Modification: Acts as a reactive monomer or cross-linking agent for synthesizing phenyl-containing silicone resins with improved heat resistance.
• Surface Treatment & Adhesion Promoters: Used to functionalize inorganic surfaces like glass, silica, or metals, improving the bonding of organic polymers and coatings.
• Intermediate for Silane Coupling Agents: Serves as a crucial building block for manufacturing more complex phenylalkoxysilane coupling agents.
• Hydrophobic Coatings: Imparts water-repellent characteristics to surfaces in protective coating formulations.
• Electronic Encapsulants & Sealants: Contributes to the formulation of high-performance silicones used in electronics for potting and sealing applications.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of active ingredients or functional excipients requiring organosilicon chemistry.

Quality Control

Our Dichloro(Ethoxy)Phenylsilane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets exacting purity and consistency standards. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance for 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 hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from moisture, strong bases, and oxidizing agents.
