“…The studies on the effect of nature of oil and unsaturation level of resin on properties of coatings based thereupon still remain scanty. In this respect oil based polyesteramide coatings have been exhaustively analysed in our earlier publications [22,23].…”

“…1,2 It has found application in the fields of medicine, leather tanning, soap industry, biodiesel, and polymeric materials. [3][4][5][6] India has the potential to produce over 150,000 tons of P. glabra seeds and about 50,000 tons of its oil. 1 Out of this, hardly one-fourth is used, whereas the rest goes to waste.…”

Poly(urethane-fatty amide) (PUPGFA) was developed to use nonedible and nondrying Pongamia glabra seed oil. The resin was synthesized by the reaction of N,N-bis(2-hydroxyethyl) P. glabra fatty amide (HEPGFA) and tolylene-2,4-diisocyanate through a one-shot technique with a minimal amount (8-10%) of organic solvent. The structural elucidation of the resin was carried out by Fourier transform infrared (FTIR), 1 H-NMR, and 13 C-NMR spectroscopic techniques, whereas the curing mechanism was confirmed by FTIR spectroscopy and differential scanning calorimetry. The solubility of the resin was studied in different polar and nonpolar solvents. Thermal analysis was carried out by thermogravimetric analysis and differential thermal analysis techniques. Antibacterial studies of HEPGFA and PUPGFA were performed in the presence of Gram-negative Salmonella and Gram-positive Staphylococcus aureus bacteria by an agar diffusion method. Physicochemical, physicomechanical, and corrosion-resistance tests were performed by standard laboratory methods. PUPGFA had good physicomechanical properties, excellent chemical/corrosion resistance, and moderate antibacterial activities.

“…It is reported that the incorporation of metal in the polymer have drastically altered their thermal stability, electrical conductivity, fracture toughness, flame retardancy, catalytic and biocidal activities, gloss, protective efficiency as well as reduction in curing temperature, and have found applicable in many areas 3, 43–52. Jayakumar et al3 and Matsuda53 have lately reviewed the work on metal incorporated‐PUs and their derivatives which are generally derived from petroleum resource.…”

It was for the first time we attempted to develop zinc and cadmium incorporated linseed oil based poly(esteramide-urethane) [Zn/Cd-LPEAUr], and investigated their structure, mechanism, and properties. The resin was synthesized in situ by the reaction of linseed oil derived fatty amide diol [HELA], divalent zinc/ cadmium acetate and toluylene-2, 4 (6), diisocyanate [TDI; 2-12 wt %] with minimal solvent. The structural elucidation of Zn/Cd-LPEAUr was carried out by FTIR, 1 H-NMR, and 13 C-NMR spectral techniques. TGA and DSC techniques were used to measure the thermal stability and curing behavior of these resins, respectively. The physicomechanical and chemical/corrosion resistance properties were investigated by standard laboratory methods. The performance of Zn/Cd-LPEAUr coating was compared with reported oil based polyesteramide. Antibacterial test of the resins were performed by agar diffusion method against E. coli and S. aureus, and compared with those of petroleum-based metal containing polyurethanes.
