Oil-modified polyesteramide resins, suitable for surface coating applications, have been synthesised, using a non-traditional semidrying niger seed oil (Guizota Olifera). N,N-bis-(2-hydroxyethyl) niger amide (HENA) has been prepared by aminolysis of the oil with diethanolamine using zinc oxide as a catalyst. HENA was reacted separately with both phthalic anhydride (PA) and isophthalic acid (IPA) in varying molar ratios to obtain two series of hydroxy-terminated polyesteramides (HTPEAs), having varying hydroxyl values. Coating compositions from these resins have been formulated by incorporation of butylated melamine formaldehyde (BMF) resin in two different ratios and their various baked film properties have been evaluated. The results reveal that the oil can successfully be used as a component of polyesteramide resins for applications in industrial stoving finishes. Further, IPA based HTPEAs show good mechanical and chemical properties compared to their PA counterparts. |
