Abstract

The epoxy resin, triglycidyl m-amino phenol, was reacted with acrylic acid to afford the vinyl ester resins. These vinyl ester resins were then reacted with toluenediisocyanate and hexamethylenediisocyanate to procure urethanized derivatives abbreviated as UTATGMAP and UTATGMAP* respectively. All these resins were characterized by their viscosity, number average molecular weight and infrared spectrophotometry. Curing characteristics for these resins were established by differential scanning calorimetry. The synthesized vinyl ester resin (TATGMAP) and urethane resins (UTATGMAP and UTATGMAP*) were polymerized on mild steel panels at 120 °C for 1 h. The resulting coated panels were characterized by scratch hardness, flexibility, impact strength and chemical resistance. The incorporation of styrene in the resin systems improves the properties of the coatings remarkably.
