Description

1-Chloroethyltrichlorosilane is a highly reactive organosilicon compound that serves as a critical intermediate in advanced material synthesis. Its value lies in its ability to introduce both chloroethyl and trichlorosilyl functional groups, enabling precise surface modification and polymer cross-linking. This chemical is essential for manufacturers in the silicone polymer, specialty coatings, and electronics industries seeking to develop materials with tailored adhesion, release, or dielectric properties.

Application

• Silicone Resin & Polymer Modification: A key monomer or cross-linking agent for synthesizing specialized silicone elastomers and resins with enhanced thermal or chemical resistance.
• Surface Treatment & Coupling Agent: Used to functionalize inorganic surfaces like glass, silica, and metals, improving the adhesion of polymers and coatings in composite materials.
• Electronics & Semiconductor Precursor: Serves as a high-purity precursor in chemical vapor deposition (CVD) processes for depositing silicon-containing thin films on semiconductor wafers.
• Hydrophobic Coating Formulation: Imparts water-repellent characteristics to surfaces in construction materials, textiles, and protective coatings.
• Intermediate for Pharmaceutical & Agrochemistry: Used in the synthesis of more complex organosilicon molecules with biological activity.
• Adhesive & Sealant Production: Enhances the performance and durability of high-end silicone-based adhesives and sealants.

Quality Control

Our 1-Chloroethyltrichlorosilane is produced under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including gas chromatography (GC), infrared spectroscopy (IR), and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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. Keep away from strong acids, bases, and oxidizing agents.
