Epoxy-amine systems are used as adhesives and paints in many industrial applications. When they were applied on metallic substrates and cured, an interphase was created between the substrate and the polymer. The interphase had chemical, physical and mechanical properties, different than the bulk phase. Amines are known to chemically react with metallic ions to form organometallic complexes. Two amines were used: the diethylenetriamine (DETA) and the isophorone diamine (IPDA). When the IPDA organometallic complexes were over the solubility limit, chelates crystallized, whereas for DETA, organometallic complexes were formed but never crystallized. The crystals were analysed. For Al-IPDA crystals, the melting point was in the range of 75-80°C. The new mechanical properties came from the crystals, that remained enclosed within the vitrified polymer; this was due to the crystals melting point, which was higher than the DGEBA-IPDA systems vitrification temperature.
