Abstract
High performance Phenol/formaldehyde-based soybean epoxy esters were prepared by reacting soybean oil fatty acids with epoxy resins which were prepared by the epoxidation of phenol /formaldehyde resins (1:1, 3:2, 2:1) using epichlorohydrin. The epoxy esters were blended with alkyd resin and the film characteristics of these blends were studied at different pigmentation level. It was found that the performance of the cured films is excellent with regard to resistance to water and solvents (acetone, ethanol, methanol, ethyl methyl ketone, toluene), while the resistance to alkali  poor and increasing the ratio of phenol /formaldehyde increase the resistance to acids. All the coating films exhibited a very good adhesion to metallic substrates, good impact, scratch hardness, flexibility and storage stability. They also provide several benefits for the manufacture of epoxy coating that include low price, versatility, minimal volatile organic content (VOC), and minimal environmental impact.
