EVALUATION OF TRADITIONAL 2K EPOXY/POLYAMIDO AMINE RESIN CHEMISTRY In this section, the traditional 2K bisphenol A epoxy- tall oil dimer acid polyamide resin system is critically evaluated. The bisphenol A epoxy in Figure 1 with the polyamido amine pictured in Figure 2 show the foundation chemistry of 2K solventborne epoxy paints. At a quick glance at these two resin structures it is apparent that the amine curing agent has many more -NH amine reactive sites per molecule than the bis A diglycidyl ether has oxirane sites.
