Description

Dichloromethyloctylsilane is a versatile organosilicon compound, specifically a chlorosilane, that serves as a crucial intermediate in the synthesis of functional silanes and silicone polymers. Its primary value lies in its ability to introduce hydrophobic, long-chain alkyl groups onto surfaces or into polymer backbones, significantly modifying material properties. This product is essential for manufacturers and R&D teams in the adhesives, sealants, coatings, and specialty chemical industries seeking to enhance water repellency, improve adhesion, or create custom silicone-based materials.

Application

• Surface Modification Agent: Used as a coupling agent or primer to impart hydrophobic properties to glass, silica, metals, and other inorganic surfaces.
• Silicone Intermediate: A key monomer or intermediate in the production of specific silicone oils, resins, and elastomers with modified rheological and surface characteristics.
• Adhesive & Sealant Formulation: Incorporated to improve moisture resistance and adhesion promotion in high-performance silicone and hybrid polymer systems.
• Nanomaterial Functionalization: Employed to graft organic chains onto nanoparticles (e.g., silica, titania) for better dispersion in organic matrices.
• Water Repellent Coatings: Acts as a precursor for creating durable water-repellent (superhydrophobic) coatings on textiles, construction materials, and electronic components.
• Chemical Synthesis: Serves as an alkylating agent or protecting group reagent in advanced organic and organometallic synthesis.

Quality Control

Our Dichloromethyloctylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and FTIR spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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 away from incompatible materials such as strong bases, oxidizing agents, and water/moisture due to its hygroscopic and reactive nature. Recommended storage temperature is between 2°C and 25°C. Use appropriate corrosion-resistant equipment for handling.
