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.

The Jatropha curcas seed oil converted to N,N-bis (2-hydroxy ethyl) fatty amide (JCHEFA) by reacting with diethanol amine. JCHEFA reacted with phthalic acid to obtained Jatropha curcas polyesteramide (JCPEA). The JCPEA treated with aluminium hydroxide to synthesized alumina filled polyesteramide (JCAPEA). The synthesized JCHEFA, JCPEA and JCAPEA have been characterized by the measurement of physic-chemical properties like specific gravity, refractive index, acid value, iodine value, soponification value. The synthesized intermediates and the final resin were also characterized by FT-IR, 1 HNMR spectroscopic analyses.

“…Various vegetable oils such as linseed, soybean, safflower, sunflower, canola, rapeseed, rubber seed, castor, tung, Annona squamosa and Pongamia glabra are used in paints and coatings industry to produced different polymers viz. alkyd, polyesteramide (Shende et al, 2004;Ahmad et al, 1999), polyetheramide (Alam et al, 2004), polyepoxies (Sharmin et al, 2007), poly (amine amides) (Alam et al, 2009b;Ahmad et al, 2006), polyurethane (Petrovic, 2008) and poly(esteramideurethane) (Alam et al, 2009a). Pongamia glabra oil is a non drying oil; only small portion of the oil is reported to be utilised in soap, leather tanning and lubricant industries (Ahmad et al, 2003).…”

Purpose -The purpose of this study is to develop poly(etherfattyamide) coatings from Pongamia glabra seeds oil utilizing a sustainable resource, which is non edible, non medicinal and goes as waste. Seed oil based poly(etherfattyamide) is used as a coating material to improve the coating properties especially gloss and alkali resistance. Design/methodology/approach -Pongamia glabra oil was first converted into N,N 0 bis 2-hydroxyethyl Pongamia glabra oil fatty amide (HEPFA). HEPFA was treated with 1,4-cyclohexanedimethanol (CHDM) to develop poly(etherfattyamide) (PEFA). PEFA was cured with (butylated melamine formaldehyde) (BMF) in different (35, 40, 45, 50) phr (part per hundred part of resin) to produce coating material. The structural elucidations of HEPFA and PEFA were carried out by FT-IR, 1 H-NMR and 13 C-NMR spectral techniques. The thermal study was performed by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), respectively. The physico-mechanical and chemical resistance/anticorrosive properties were investigated by standard laboratory methods. Findings -The authors developed a good coatings material from a sustainable resource. The physico-mechanical and anticorrosive performance evaluation exhibits satisfactory results. PEFA-BMF coatings material showed good alkali resistance and high gloss. The thermal studies showed that PEFA-BMF45 may be safely used up to 2258C. Practical implications -BMF modified PEFA coatings showed the highest scratch hardness 3.5 kg, flexibility (1/8 inch conical mandrel bend test) and gloss at 458 is 76-82. Among all, PEFA-BMF45 showed the best physico-mechanical and chemical resistance performance. Thus, it may be used as an efficient coating material. Originality/value -The synthesis of BMF modified PEFA from Pongamia glabra oil using 1,4-cyclohexanedimethanol has been studied for the first time providing a new approach to utilize a non edible seed oil -a sustainable resource.
