Polyesteramide (PEA) and alumina-filled polyesteramide (APEA) resins were synthesized from N,N′-bis(2 hydroxyethyl) linseed amide. The FTIR, 1H-NMR, DSC, TGA, thermal curing, and physico-chemical characterization of these polymers were carried out. The coatings of PEA and APEA were made on mild steel strips. The mechanical behavior and protective efficiency of these coatings in acid, alkali, and organic solvents were investigated. APEA coatings have been found to show superior performance in comparison to other coatings.
