“…8 The bands at 2932 cm −1 and 2891 cm −1 can be ascribed to the −C−H asymmetric and symmetric stretching absorptions of the −CH 3 and −CH 2 groups of fatty acid present in alkyd. 34 In addition, the band at 1655 cm −1 has been assigned to −CHCH stretching vibration of double bond. The presence of a characteristic band at 1596 cm −1 is evidence for the transformation of a terminal carboxylic group to a carboxylate anion.…”

The surface coating industry is globally involved in developing useful, eco-friendly, and VOC (volatile organic compounds)-free coating systems, which exhibit promising physico-mechanical and corrosion protective performance. Herein, we report the synthesis of butylated melamine formaldehyde (BMF)-modified soy alkyd (SA-BMF). The structural elucidation and molecular weight of soy alkyd (SA) and SA-BMF resin was carried out by FT-IR, 1 H NMR, and 13 C NMR spectroscopy and gel permeation chromatography (GPC) techniques. The physico-chemical and physico-mechanical properties were tested by standard protocols. Initial decomposition temperature was measured by thermogravimetric analysis (TGA). The curing study and glass transition temperature were assessed by differential scanning calorimetry (DSC). Hydrophobicity of the coatings was measured in terms of contact angle. The anticorrosion performance of SA-BMF was studied experimentally using polarization techniques and electrochemical impedance spectroscopy (EIS), while the antimicrobial efficacy of the same were tested against Gram positive bacterium Staphylococcus aureus (S. aureus) and Gram negative bacterium Escherichia coli (E. coli) by the agar diffusion method. Overall, our studies revealed that the waterborne SA-BMF coating exhibited higher scratch resistance, impact resistance (150 lb/in.), and bend tests (flexibility retentive 1/8 in.), along with good antibacterial activity and anticorrosive performance. These coatings also find safe usage up to 200°C.

“…Castor oil is also distinguished from other vegetable oils by its high specific gravity and hydroxyl value. Therefore, a lot of research work is being carried out towards the production of vegetable oil based polymeric materials possessing good physical and chemical properties [5][6][7]. Moreover, castor oil based polymers are biodegradable, cheap, easy to modify, and easily available in large quantities [8].…”

Castor oil based polyesteramide (CPEA) resin has been successfully synthesized by the condensation polymerization of N-N-bis (2-hydroxyethyl) castor oil fatty amide (HECA) with terephthalic acid and further modified with different percentages of 7, 9, 11, and 13 wt.% of toluene-2,4-diisocyanate (TDI) to obtain poly(urethane-esteramide) (UCPEA), via addition polymerization. TiO2(0.1, 0.2, 0.3, 0.4, and 0.5 wt%) nanoparticles were dispersed in UCPEA resin. The structural elucidation of HECA, CPEA, and UCPEA has been carried out using FT-IR,1H-NMR, and13C-NMR spectroscopic techniques while physicochemical and physicomechanical properties were investigated by standard methods. Thermal stability and molecular weight of UCPEA have been assessed by thermogravimetric analysis (TGA) and gel permeation chromatography (GPC), respectively. Furthermore, the corrosion behavior of UCPEA coatings on mild steel has been investigated by potentiodynamic polarization measurements in different corrosive environments (3.5 wt% HCl, 5 wt% NaCl, 3.5 wt% NaOH, and tap water) at room temperature and surface analysis by scanning electron microscope (SEM) and energy dispersive X-ray (EDX). The antibacterial activities of the UCPEA were tested against bacteria and fungi by agar disc diffusion method. The results of this study have revealed that UCPEA nanocomposite coatings exhibit good physicomechanical, anticorrosion and antimicrobial properties, which can be safely used up to 200°C.

“…The equivalent epoxide weight to anhydride equivalent weight ratio (ratio EEW:AEW) is considered using the groups with cross-linking capacity that both species contain in order to obtain an equivalent mass relationship that will enable us to identify the optimum quantities of epoxidized vegetable oil and hardener to be mixed together. There is a direct relationship between the cross-linking in the internal structure and the mechanical and thermal behavior of the epoxy resins [14,[21][22][23].…”

Epoxidized soybean oil (ESBO), obtained from a renewable resource was used in the production of thermoset resins. Samples of the ESBO were initially treated with maleic anhydride, equal mixture of catalyst (1,3‐butanediol anhydrous and benzyldimethylamine) and the mixture was cured for 5 h at different temperatures. After the curing process, the ratio between the ESBO and the anhydride (ratio EEW:AEW) was evaluated in terms of the different mechanical properties produced using flexural, Shore D hardness and Charpy impact tests. The sample with the best mechanical properties was that with an EEW:AEW ratio of 1:1.0 which leads to best balanced behavior and this could be representative for the maximum crosslinking degree. Also, thermal characteristics were evaluated during the crosslinking process using differential scanning calorimetry, In addition, other thermal characteristics of the cured materials were obtained by determining the heat deflection temperature and the Vicat softening temperature. The coefficient of thermal expansion was determined using thermo‐mechanical analysis. In accordance with the mechanical behavior, the best thermal properties were obtained for samples with an EEW:AEW ratio of 1:1.0. As a result of this work, a biologically based epoxy resin with good mechanical properties and flexibility was obtained.
