Description

(3-Chloropropyl)Ethoxydimethylsilane is a versatile organosilicon compound that serves as a crucial intermediate in the synthesis of functionalized silanes and silicone polymers. Its bifunctional structure, featuring both a reactive chloropropyl group and a hydrolyzable ethoxysilyl group, makes it a key building block for introducing specific properties into materials. This product is essential for manufacturers in the silicone, adhesive, and specialty chemical industries seeking to enhance product performance through surface modification and cross-linking.

Application

• Silicone Intermediate: A key monomer for the synthesis of modified polysiloxanes and silicone elastomers with specific functional groups.
• Surface Treatment Agent: Used to modify the surface of inorganic materials like glass, silica, and metals to improve adhesion and compatibility with organic polymers.
• Coupling Agent: Acts as a bridge between organic and inorganic phases in composite materials, enhancing mechanical properties and durability.
• Adhesive & Sealant Formulation: Incorporated to improve the bonding strength, moisture resistance, and flexibility of adhesives and sealants.
• Rubber & Plastic Additive: Used as a cross-linking agent or processing aid to modify the properties of rubber and plastic compounds.
• Pharmaceutical & Agrochemical Intermediates: Serves as a precursor in the synthesis of more complex molecules for pharmaceutical and agrochemical applications.

Quality Control

Our (3-Chloropropyl)Ethoxydimethylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC (Gas Chromatography) and NMR (Nuclear Magnetic Resonance), to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee compliance with your specifications and industry 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). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain quality. Keep away from strong acids, bases, and oxidizing agents.
