Description

Dichloro-n-Dodecylmethylsilane is a versatile organosilicon compound, specifically a chlorosilane, that serves as a crucial intermediate in the synthesis of functional silanes and silicone polymers. Its value lies in its ability to introduce a long-chain dodecyl group and a reactive chlorosilane functionality, enabling surface modification and polymer cross-linking. This product is essential for manufacturers in the silicone, coatings, and specialty chemical industries seeking to impart hydrophobic, release, or compatibilizing properties to their materials.

Application

• Silicone Polymer Synthesis: A key monomer for introducing long alkyl chains into silicone copolymers, modifying flexibility, hydrophobicity, and surface properties.
• Surface Treatment Agent: Used to hydrophobize inorganic surfaces like silica, glass, and metals, improving water repellency and compatibility with organic matrices.
• Release Coating Intermediate: Serves as a precursor for formulating silicone-based release coatings for labels, tapes, and packaging materials.
• Coupling Agent: Acts as a bridging molecule to enhance adhesion between organic polymers and inorganic fillers in composite materials.
• Specialty Additive Synthesis: Intermediate for producing custom silane additives for paints, coatings, and sealants to improve performance.
• Research & Development: Used in laboratories for developing new organosilicon compounds with tailored properties for advanced material science.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and oxidizing agents.
