Description

Dichloromethyltetradecylsilane is a high-purity organosilicon compound, specifically a chlorosilane with a long alkyl chain. This chemical serves as a critical intermediate and surface modifying agent, valued for its ability to impart hydrophobic and oleophobic properties to materials. It is essential for manufacturers and R&D teams in the specialty chemicals, advanced materials, and surface coating industries seeking to enhance product performance through tailored surface chemistry.

Application

• Surface Modification Agent: Key intermediate for synthesizing hydrophobic and oleophobic coatings on glass, silica, and metals.
• Silicone Polymer Synthesis: Used as a monomer or chain extender in the production of specialty silicone oils, resins, and elastomers with long alkyl side chains.
• Chromatography Stationary Phases: Employed in the derivatization of silica gel to create reversed-phase columns for HPLC and GC analysis.
• Adhesion Promoter: Functions as a coupling agent to improve the bond between organic polymers and inorganic substrates.
• Nanomaterial Functionalization: Used to modify the surface of nanoparticles (e.g., silica, titania) to control dispersion and compatibility in composite materials.
• Water Repellent Treatments: A precursor for formulations applied to textiles, construction materials, and paper to confer water resistance.
• Release Coatings: Intermediate in the manufacture of silicone-based release liners for labels and adhesive tapes.
• Research & Development: Serves as a versatile building block in organic and organometallic synthesis for academic and industrial research.

Quality Control

Our Dichloromethyltetradecylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and oxidizing agents.
