Description

Cyclohexyltrichlorosilane CAS NO 98-12-4 is a highly reactive organosilicon compound characterized by a cyclohexyl group bonded to a trichlorosilyl moiety. This chemical is a critical intermediate in the synthesis of various silicone-based materials, valued for its ability to introduce hydrophobic and organofunctional properties. It is primarily utilized by manufacturers in the silicone polymer, specialty chemical, and advanced materials industries for creating coupling agents, surface modifiers, and silane precursors.

Application

• Silicone Coupling Agent: A key intermediate for manufacturing silane coupling agents used to improve adhesion between organic polymers and inorganic surfaces like glass, minerals, and metals.
• Surface Hydrophobization: Used to impart water-repellent (hydrophobic) characteristics to surfaces in coatings, textiles, and construction materials.
• Silicone Resin & Polymer Synthesis: Serves as a monomer or cross-linking agent in the production of specialty silicone resins, elastomers, and modified polymers.
• Chemical Intermediate: Acts as a versatile building block in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals.
• Adhesive & Sealant Formulations: Incorporated to enhance the moisture resistance and durability of industrial adhesives and sealants.
• Nanomaterial Functionalization: Used to modify the surface of nanoparticles (e.g., silica, metal oxides) to improve dispersion and compatibility in composite materials.

Quality Control

Our Cyclohexyltrichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and FTIR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
