Cycloaliphatic Diepoxide

Definition - What does Cycloaliphatic Diepoxide mean?

Cycloaliphatic diepoxide is a binary monomer additive used in the synthesis of acrylic thermosetting latex coatings. It functions as a cross-linking agent. The formula of this polymer is 3,4-epoxycyclohexyl methyl-3',4'-epoxycyclohexane carboxylate. In curing of surface coatings by UV radiation, it is useful as a base and improves the adhesion of the brittle epoxy resin matrix and the elastomeric domain. It's mostly used in experiments to provide formulations.

Corrosionpedia explains Cycloaliphatic Diepoxide

Cycloaliphatic diepoxide is an epoxy group. It is also used with epoxidized natural rubber and dissolved in glyddyl methacrylate (GMA) to form coating systems. They are used with the mentioned materials to address the issue of slow reaction and brittleness of highly cross-linked or rigid network cationic photo polymerizations of epoxides. It basically takes control of the mixtures required to participate in photo polymerization, which involves the conversion of monomers into polymers.

They have better mechanical and physical properties as compared to mono-functional ones. Their main use was to act as UV resistors in outdoor electrics. In cationic polymerizations, they are slow and reach low conversions. Naturally, they are brittle in nature, therefore this property can be controlled by oligomers. The glossy exterior property of coatings desired on automotive and printing applications is attributed by the use of cycloaliphatic diepoxide in the coating or adhesives. This is due to high glass transition temperature and high Young’s modulus.
