HENGDA-M3123 - 2-(3,4-Epoxycyclohexyl)ethyltrimethoxysilane

HENGDA-M3123

2-(3,4-Epoxycyclohexyl)ethyltrimethoxysilane is an organosilane coupling agent that contains an epoxy group attached to an ethyl chain and a trimethoxysilane group.
Chemical Structure:
Epoxy group (3,4-Epoxycyclohexyl): Contains an epoxy functional group, which is reactive and can participate in cross-linking reactions.
Ethyl chain (-C₂H₅): Serves as the main backbone for the molecule.
Trimethoxysilane group (-Si(OCH₃)₃): This group is hydrolysable, allowing it to bond strongly to inorganic surfaces.

Applications

1.2-(3,4-Epoxycyclohexyl)ethyltrimethoxysilane is an epoxy-functional coupling agent that provides storage-stable and non-yellowing adhesion-promoting effect. It is suitable as an adhesion promoter for polysulfide, polyurethane, epoxy, acrylic sealants and adhesives. It can significantly improves the adhesion and water resistance of sealants and adhesives to inorganic materials such as glass, metal, and concrete.

2.It can improve the adhesion between epoxy resin and substrate, improve the electrical properties of epoxy resin electronic materials, potting materials, and printed circuit boards and improve Gas performance, especially wet electrical performance.

3.As a surface treatment agent for inorganic fillers, It is suitable for silica micropowder, glass microspheres, aluminum hydroxide, clay, talcum powder, wollastonite, silica, quartz powder, metal powder, etc.

4.2-(3,4-Epoxycyclohexyl)ethyltrimethoxysilane is used to water-based coatings such as acrylic and polyurethane, it can be used as an adhesion promoter and crosslinking agent to improve adhesion strength, water resistance, abrasion resistance, and scrub resistance of the coating. Compared with HENGDA-M3133, this product can achieve a longer storage period in water-based resins.
