We have reported that the application of thermal latent hardener with aliphatic amine structures to cyanate ester resin/epoxy resin provides rapid curing at low temperature of approximately 100 ℃, and the networked polymers have high physical properties and adhesive strength. In this study, we investigated the adhesive behavior, the coefficient of linear thermal expansion, and the volume change by networked polymers from the viewpoint of the curing reaction or crosslinked structure. As the result, it was found that the hydroxyl groups generated by the ring-opening reaction of the epoxide contributed to the high adhesive strength to the substrate. The rigid triazine structure by trimerization of cyanate esters caused to decrease the coefficient of linear thermal expansion and to increase the curing shrinkage.
