Description

3-Cyclohexenyltrimethoxysilane is a specialized organosilicon compound featuring a reactive cyclohexenyl group and hydrolyzable methoxy silane functionality. This unique structure makes it a valuable coupling agent and surface modifier, enhancing the adhesion and compatibility between organic polymers and inorganic substrates. It is essential for manufacturers in the composites, coatings, and sealants industries seeking to improve material performance and durability. The compound is supplied under strict quality control to ensure batch-to-batch consistency for demanding industrial applications.

Application

• As a coupling agent in fiberglass-reinforced plastics and mineral-filled composites to improve mechanical strength and moisture resistance.
• As a surface treatment agent for glass, silica, and metals to promote adhesion in coatings, inks, and adhesives.
• As a key intermediate in the synthesis of more complex silane derivatives and specialty polymers.
• In the formulation of moisture-curable sealants and RTV silicones to modify cross-linking and elastomeric properties.
• For hydrophobic modification of surfaces and nanoparticles to control wettability and dispersion.
• In tire and rubber manufacturing as a silane coupling agent to enhance filler-rubber interaction and reduce rolling resistance.

Quality Control

Our 3-Cyclohexenyltrimethoxysilane is manufactured under a rigorous quality management system. Each production batch undergoes comprehensive analytical testing, including assay and impurity profiling, to ensure it meets precise specifications for industrial applications. A Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with every shipment to guarantee traceability and compliance with your quality requirements.

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 moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain product integrity.
