Abstract

We describe a new amine-hardener that enables intrinsic thermally activated healing in epoxy-amine coatings. A hetero-Diels Alder (HDA) adduct bridges biosourced fatty acids and serves as the thermoreversible linker. We validated the thermal reversion of the adduct in solution and the HDA-containing diamine served as a drop-in replacement for commercial hardeners.
