Description

2-(3,4-Epoxycyclohexyl)Ethyltriethoxysilane is a high-purity organosilane coupling agent featuring a reactive epoxycyclohexyl group and hydrolyzable ethoxysilyl groups. This dual functionality makes it an essential component for enhancing the adhesion between inorganic substrates and organic polymer matrices. It is primarily used by formulators and manufacturers in the advanced composites, coatings, adhesives, and electronics industries to improve mechanical properties, durability, and moisture resistance in their final products.

Application

• Coupling Agent for Composites: Enhances the interfacial bonding between glass, carbon, or mineral fibers and epoxy, polyester, or acrylic resin systems, significantly improving mechanical strength and fatigue resistance.
• Surface Modification for Fillers: Used to treat silica, alumina, and other inorganic fillers to improve their dispersion and compatibility within polymer matrices, reducing viscosity and enhancing composite performance.
• Adhesion Promoter in Coatings & Inks: Formulated into primers and coating systems to promote adhesion to difficult substrates like metals, glass, and plastics, especially in harsh environmental conditions.
• Crosslinking Agent for Silicones: Serves as a crosslinker or adhesion promoter in silicone sealants, RTV (Room Temperature Vulcanizing) rubbers, and encapsulants, particularly where bonding to non-porous surfaces is required.
• Electronic Encapsulation & Molding Compounds: Improves the adhesion and moisture resistance of epoxy molding compounds and potting agents used to protect semiconductors and electronic components.
• Fiber Optic Coatings: Applied in coatings for optical fibers to enhance the adhesion between the glass fiber and the protective secondary coating, ensuring long-term reliability.

Quality Control

Our production of 2-(3,4-Epoxycyclohexyl)Ethyltriethoxysilane adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including GC (Gas Chromatography) for purity and assay, IR (Infrared Spectroscopy) for identification, and Karl Fischer titration for moisture content, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee consistency and support your quality assurance protocols.

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 / 59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain product integrity. Keep away from strong acids, bases, and oxidizing agents.
