Description

2-Chloroethyltriisopropoxysilane is a versatile organosilicon compound, specifically a chlorinated alkoxysilane, that serves as a critical coupling agent and intermediate in advanced material synthesis. Its molecular structure, featuring both reactive chloroethyl and hydrolyzable isopropoxy groups, enables it to form durable bonds between organic polymers and inorganic substrates. This product is essential for manufacturers in the adhesives, sealants, coatings, and composite materials industries seeking to enhance material performance, adhesion, and durability.

Application

• Surface Modification and Coupling Agent: Used to treat glass fibers, minerals, and fillers to improve their compatibility and adhesion with polymer matrices in composites.
• Adhesive and Sealant Formulations: Acts as an adhesion promoter, enhancing bond strength and moisture resistance in silicone, epoxy, and polyurethane systems.
• Protective and Functional Coatings: Employed as a crosslinking agent or precursor to create hydrophobic, corrosion-resistant, and durable surface coatings.
• Silicone Resin and Rubber Intermediate: Serves as a key monomer or modifying agent in the synthesis of specialty silicone polymers with tailored properties.
• Fiber Sizing: Applied as a sizing agent on glass or carbon fibers to protect filaments and improve resin wet-out and interfacial bonding.
• Nanomaterial Functionalization: Used to graft organic functionalities onto silica nanoparticles and other inorganic nanomaterials for advanced applications.

Quality Control

Our 2-Chloroethyltriisopropoxysilane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by GC or titration, identity confirmation (IR), and control of key impurities. A Certificate of Analysis (COA) detailing all test results is provided with every 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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation by atmospheric moisture. Keep away from heat, sparks, and open flame.
