Alkyd resins with 80% solids using SOFA and DCOFA combination were successfully synthesized with varying percentage of DPE content. The rheological trends at different concentrations indicate the highly branched structure of alkyds with the increase in DPE content. The higher polydispersity and increasing branched network with increased DPE content in the resin helped to achieve better flow/leveling and film hardness. The gloss and gloss retention of dry films were also found to be improved with branching as depicted by AFM and QUV results. EIS study reveals the improved corrosion resistance with increasing DPE content in the resin backbone.
