Description

Trichloro(2-Ethylhexyl)Silane is a versatile organosilicon compound that serves as a key intermediate in the synthesis of functional silanes and silicone polymers. Its value lies in its ability to introduce the bulky 2-ethylhexyl group, which imparts unique properties like hydrophobicity and steric hindrance to final materials. This chemical is essential for R&D chemists and manufacturers in the silicone, specialty chemical, and advanced materials sectors seeking to develop custom surface modifiers, coupling agents, and polymer additives.

Application

• Silicone Polymer Modification: Acts as a monomer or chain terminator to introduce hydrophobic, branched alkyl chains into silicone oils, rubbers, and resins, modifying their rheological and surface properties.
• Surface Treatment Agent: Used to functionalize inorganic surfaces like silica, glass, or metals, creating a hydrophobic monolayer that improves compatibility with organic matrices.
• Coupling Agent Synthesis: A crucial precursor for manufacturing specialized silane coupling agents with enhanced solubility and steric bulk for composite materials.
• Pharmaceutical & Agro-Intermediate: Serves as a building block in the synthesis of more complex organosilicon molecules for pharmaceutical or agrochemical applications.
• Water Repellent Formulations: Incorporated into coatings and sealants to confer long-lasting water repellency and weather resistance.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new organosilicon chemistry and material science applications.

Quality Control

Every batch of Trichloro(2-Ethylhexyl)Silane is produced and tested under strict quality management protocols to ensure consistency and reliability for industrial applications. Our standard quality assurance includes verification of identity, purity, and critical physical parameters. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment, and we can accommodate requests for testing against custom specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-25°C. Keep away from strong acids, bases, and oxidizing agents.
