Description

Cyclohexylethyldimethoxysilane is a versatile organosilicon compound, specifically a dialkoxysilane, that serves as a critical coupling agent and surface modifier. Its molecular structure, featuring both a cyclohexylethyl group and reactive methoxy silane functionalities, enables it to bridge organic and inorganic materials, enhancing adhesion, dispersion, and compatibility. This product is essential for manufacturers in the silicone polymers, advanced composites, and specialty coatings industries seeking to improve material performance and durability.

Application

• Silicone Rubber & Sealants: Acts as a crosslinking agent and adhesion promoter, improving the mechanical properties and bond strength of silicone-based formulations.
• Filled Polymer Composites: Functions as a coupling agent for mineral-filled (e.g., silica, clay) plastics and rubbers, enhancing filler dispersion and composite strength.
• Surface Treatment & Primers: Used to modify the surface of glass, metals, and minerals to improve the adhesion of subsequent coatings, paints, or adhesives.
• Fiberglass & Reinforced Plastics: Sizes and treats glass fibers to enhance the interfacial bond with polymer matrices like epoxy or polyester, increasing laminate durability.
• Water Repellents: Imparts hydrophobic properties to construction materials like concrete, masonry, and stone.
• Pharmaceutical & Agrochemical Intermediates: Serves as a key synthetic building block (synthon) in the production of more complex silane-based active ingredients.

Quality Control

Our Cyclohexylethyldimethoxysilane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC (Gas Chromatography) for purity and assay and FTIR (Fourier-Transform Infrared Spectroscopy) for structural identification, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and consistency for your production processes.

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 and highly volatile nature, containers must be kept tightly sealed after opening to prevent moisture absorption and evaporation. Keep away from heat, sparks, and open flame.
