Abstract
Thermal latency of zinc 2-ethylhexanoate catalyst in the presence of triethanolamine and its application to hemiacetal ester / epoxide crosslinking system were examined. A novel crosslinking system consisting of oligomer having hemiacetal ester moiety and epoxy polymer could be constructed by zinc 2-ethylhexanoate-triethanolamine as a thermal latent initiator. Both thermal dissociation of the hemiacetal ester moiety and esterification of the generated carboxyl group with epoxy group were also accelerated in the presence of this initiator. The zinc 2-ethylhexanoate-triethanolamine served as an useful thermal latent initiator for hemiacetal ester / epoxide crosslinking system.
