Thermal conductive composites prepared by addition of several ceramic fillers to thermally cationic curing cycloaliphatic epoxy resins

Novel composite coatings prepared from3,4-epoxy cyclohexylmethyl 3,4-epoxycyclohexane carboxylate (ECC) and different ceramic fillers have been prepared to improve the thermal dissipation of electronic devices. As latent cationic initiator, a benzylanilinium salt with triethanolamine has been used,...
