Description
Summary:•UV curable coating materials from jatropha oil and palm oil were prepared.•The results indicate that more glossiness, shorter reaction time in jatropha oil-based oligomers.•The properties of jatropha- based oligomer is superior than palm oil based in UV curable coating.•The study leads to conclude that green coating have potential for over print varnish application. We report a novel family of acrylate-functional monomers/oligomers derived from epoxidized jatropha oil using acrylic acid. Acrylated epoxy jatropha oil-based polymer was synthesized in two steps reaction. Oligomers were coated on glass substrate and cross-linked afterwards by UV irradiation. The coating properties such as gloss, scratch hardness and chemical resistance were evaluated via standard methods. A comparative study of jatropha and palm oil based acrylate UV coatings was conducted. The most important and economic method for the acrylation of epoxidized jatropha oil requires a 6-h reaction time compared to palm oil that requires a 20-h reaction time. The acrylated epoxidized jatropha oil exhibited improved glossiness, UV curing time and hardness over the acrylated epoxidized palm oil.
