Description

1-Dichloromethyl(Dimethyl)Silyloxyoctadecane is a specialized organosilicon compound, specifically a chlorosilane derivative with a long alkyl chain, offering unique reactivity and surface-modifying properties. This chemical serves as a valuable intermediate and functional additive, enabling precise molecular design in advanced material synthesis. It is primarily utilized by R&D chemists and process engineers in the silicone polymer, specialty coatings, and surface treatment industries to impart specific hydrophobic, release, or adhesion-promoting characteristics.

Application

• Silicone Polymer Modification: Acts as a functional monomer or chain extender to introduce long alkyl chains, modifying the hydrophobicity, lubricity, and flexibility of silicone elastomers and resins.
• Surface Treatment Agent: Used to create hydrophobic and oleophobic coatings on glass, metals, and ceramics, providing water repellency and easy-clean properties.
• Release Coatings: Serves as a key intermediate in the formulation of high-performance silicone release liners for pressure-sensitive adhesives and industrial molding.
• Adhesion Promoter: Functions as a coupling agent to improve the bond between organic polymers and inorganic substrates like minerals or metals in composite materials.
• Lubricant & Flow Additive: Incorporated into plastics, rubbers, and coatings to reduce surface friction and improve processing characteristics.
• Research & Development: A crucial building block in organic and organometallic synthesis for developing novel materials with tailored surface energies.

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 material is hygroscopic (moisture-sensitive) and may react with strong acids or organic solvents; therefore, it must be kept under an inert atmosphere (e.g., nitrogen or argon) and separated from incompatible materials.
