Description

1-Dimethyl(Chloromethyl)Silyloxyoctadecane is a specialized organosilicon compound featuring a long alkyl chain and a reactive chloromethylsilyl group. This unique structure makes it a valuable intermediate for introducing hydrophobic and organofunctional properties into various materials. It is primarily utilized in the synthesis of advanced silicone polymers, surface modifiers, and adhesion promoters. Industries involved in specialty chemicals, coatings, and material science will find this compound essential for developing products with enhanced performance characteristics.

Application

• Silicone Polymer Modification: Acts as a key monomer or cross-linking agent in the synthesis of custom silicone oils, resins, and elastomers with tailored properties.
• Surface Treatment Agent: Used to impart durable water repellency, release properties, or specific surface energy to textiles, paper, and fillers like silica.
• Adhesion Promoter: Enhances the bonding between organic polymers and inorganic substrates (e.g., glass, metals) in coatings, sealants, and composite materials.
• Intermediate for Functional Silanes: Serves as a precursor for further chemical reactions to create other organosilane coupling agents with different functional groups.
• Lubricant & Grease Additive: Incorporated into formulations to improve lubricity, thermal stability, and water resistance.

Quality Control

Our production of 1-Dimethyl(Chloromethyl)Silyloxyoctadecane adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (GC/HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure consistency and high purity. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment to guarantee reliable performance in your formulations.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
