Description

Cyclohexyldiethoxymethylsilane is a versatile organosilicon compound, specifically a cyclohexyl-functional alkoxysilane, widely used as a key coupling agent and surface modifier. Its primary value lies in its ability to form strong, durable bonds between inorganic substrates and organic polymers, significantly enhancing material performance. This product is essential for manufacturers in the adhesives, sealants, coatings, and advanced composite materials industries seeking to improve adhesion, hydrophobicity, and mechanical properties.

Application

• Adhesive & Sealant Formulation: Acts as an adhesion promoter, particularly for silicone-based and hybrid polymer systems, improving bond strength to glass, metals, and minerals.
• Surface Treatment & Coatings: Used to modify the surface of fillers (e.g., silica, glass fibers) and pigments to enhance dispersion, compatibility, and moisture resistance in polymer matrices.
• Composite Materials: Serves as a coupling agent in fiber-reinforced plastics (FRP) and mineral-filled composites to improve interfacial bonding and mechanical strength.
• Hydrophobic Coatings: Imparts water-repellent properties to surfaces in construction materials, stone, and concrete protectants.
• Silicone Resin Modification: Used as a crosslinking agent or modifier in the synthesis of specialty silicone resins and elastomers.
• Chemical Synthesis: Functions as a protected intermediate or building block in organic and organometallic synthesis.

Quality Control

Our production of Cyclohexyldiethoxymethylsilane follows stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including gas chromatography (GC) for assay and impurity profiling. A Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment to support your quality assurance and regulatory needs.

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 nature, containers must be kept tightly sealed to prevent moisture absorption, which can lead to hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
