It reacts by cationic polymerization using thermolatent photoinitiators to form crosslinked insoluble thermosets.

Formulations based on cycloaliphatic epoxy resins such as ECC are known to form by curing thermosets with high heat and chemical resistance and good adhesion.

[2] The homopolymerization of ECC is based on radiation curing, which proceeds via a photochemical formation of a super acid and subsequent cationic polymerization.

It is therefore the object of research to find cationic polymerizable monomers with higher polymerization rate but same performance.

[2] Cationically crosslinked ECC is used in a variety of industrial applications, due to its low viscosity, excellent electrical properties and high reliability among others as an electrical insulator, as coating and adhesive or as printing ink.
