dc.description.abstractJatropha curcas Linnaeus (JCL) seed oil was utilized in the preparation of four sets of alkyd resin (35%, 50%, 60% and 75% oil formulations) using a two-stage alcoholysis–polyesterification method. The rates of polyesterification depended on the amount of oil used during synthesis. The properties of the alkyds were evaluated. The range of solidification times was between 278 and 442 s; also the range of film thickness was between 0.014 and 0.08 mm, and the alkyds were readily soluble in turpentine, xylene and butanol. Inclusion of cobalt naphthenate as drier and outdoor temperature (37 °C ± 2) improved the drying properties of all the alkyds. The colours of white gloss paints formulated from the alkyds, considering a pigment-volume concentration of 20.67% in the gloss paint formulation, compared well with that of a paint formulated using a commercial alkyd sample. 1H NMR analysis confirms the expected structure of the alkyds.en_US
