Bisester namely 1,1'-(1-methyl ethylidene) bis[4-{1-(1-imino-4-ethyl benzoate)-2-propa-nolyloxy}] benzene was synthesized by the reaction of epoxy resin (DGEBA) and 4-aminoethyl benzoate (4-AEB) using triethyl amine as catalyst. The synthesized bisester was reacted with three different aliphatic diamines viz; diethylene triamine (DETA), triethylene tetramine (TETA) and polyethylene amine (PEA) to obtained respective poly-amide resins (PAs) abbreviated as DGEBA-4-AEB: DETA, DGEBA-4-AEB: TETA and DGEBA-4-AEB : PEA respectively. The PAs synthesized were used as a curing agent for the difunctional epoxy resin (DGEBA) and trifunctional epoxy resin (TGPAP) in three different ratios. Using triethyl amine as a catalyst and PAs as a curing agent, DGEBA and TGPAP were polymerized on mild steel panels at 120d`C for 1 hr. The coated panel thus obtained were tested for scratch hardness, flexibility, impact strength and chemical resistancy. It appears from the results for the epoxy resins, epoxy based polyamides can successfully be used as a curing agent for the coating application. |
