Cycloaliphatic resin
Webbisphenol A epoxy resins or epoxy phenol novolacs. This performance has been extended to the cure of cycloaliphatic epoxy resins for encapsulating high performance electronic components, including light emitting diodes. Examples of these cycloaliphatic epoxies are provided below: 3,4-epoxycyclohexylmethyl-3',4'-epoxy cyclohexanecarboxylate WebCationic curing is a photoinitiated, acid catalyzed ring opening polymerization of epoxy resins using onium salts. On exposure to UV light energy and in the presence of a hydrogen donor (typically the resin components of a formulation) cationic photoinitiators produce a long lived acidic species.
