Description

Dichlorohexadecylmethylsilane is a high-purity organosilicon compound, specifically a long-chain alkylchlorosilane. This chemical is a critical intermediate for introducing hydrophobic, long-chain alkyl groups onto surfaces or into polymer matrices, significantly altering material properties. It is essential for manufacturers and R&D teams in the specialty chemicals, advanced materials, and surface treatment sectors seeking to modify surface energy, enhance lubricity, or create specific release characteristics.

Application

• Surface Modification Agent: A key precursor for creating hydrophobic, oleophobic, or low-surface-energy coatings on glass, silica, metals, and polymers.
• Silicone Polymer Synthesis: Serves as a monomer or modifier in the production of specialty silicone oils, resins, and elastomers to impart specific chain length and properties.
• Coupling Agent: Used to improve adhesion and compatibility between organic polymers and inorganic fillers or substrates.
• Release Coatings: Employed in the formulation of internal and external release agents for industries like plastics molding and pressure-sensitive adhesives.
• Nanomaterial Functionalization: Used to graft long alkyl chains onto nanoparticles (e.g., silica, quantum dots) to control dispersion in organic solvents or polymer hosts.
• Water Repellents: A building block for formulations that provide water-resistant properties to textiles, leather, paper, and construction materials.
• Lubricant Additive: Can be used to develop specialty lubricants and anti-friction coatings due to its long hydrocarbon chain.
• Research & Development: A valuable reagent in organic synthesis and materials science for developing novel functional materials.

Quality Control

Our Dichlorohexadecylmethylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and FTIR spectroscopy, to ensure high chemical purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are 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). 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.
