Purpose -The purpose of this paper is to develop pyridine polyesteramide coatings from Linseed (Linum ussitatissimum) seeds oil for the utilisation of a sustainable resource as coating material, as well as to improve the coating properties. Design/methodology/approach -Linseed oil was first converted into N,N bis 2-hydroxyethyl linseed oil fatty amide (HELA). The resin was synthesized by the reaction of linseed oil fatty amide diol with 2,3-pyridine di carboxylic acid to develop pyridine polyesteramide (Py-PEA) and further treated with poly(styrene-co-maleic anhydride)(SMA) in different phr (part per hundred part of resin). The structural elucidation of Py-PEA was carried out by FT-IR, 1H-NMR and 13C-NMR spectral techniques. The thermal stability and curing behaviour of the resin were determined by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), respectively. The physico-mechanical and anticorrosive properties were investigated by standard laboratory methods. Findings -The authors developed a good anticorrosive coating material from sustainable resource. The physico-mechanical and anticorrosive performance evaluation exhibited satisfactory results. The approach facilitated curing to occur at ambient temperature and the thermal studies revealed that Py-PEA-SMA-45 might be safely used up to 1408C. Practical implications -Poly(styrene-co-maleic anhydride) modified pyridine polyesteramide coatings showed the highest scratch hardness 3.0 kg, flexibility (1/8 inch canonical mandrel bend test) and gloss at 458 is 62-64. Among all, Py-PEA-SMA 45 showed the best physico-mechanical and chemical resistance performance. Thus, the resin may be used as an effective coating material. Originality/value -The paper shows that the synthesis of polyesteramide resin from vegetable oil provides a new way to utilize a renewable resource based raw material.
