Fatty Acid Methyl Ester as Reactive Diluent in Thermally Cured Solvent-Borne Coil-Coatings: The Effect of Fatty Acid Pattern on the Curing Performance and Final Properties

Four different fatty acid methyl esters (FAMEs): rape seedmethyl ester (RME), tall oil methyl ester (TOME), and two types of linseed oilmethyl ester (Linutin) have been studied as reactive diluents in thermally cured solvent-borne coil-coatings. The purpose was to evaluate the effect of fatty acid methyl ester structure on the curing performance and final properties of the coating. The permanent incorporation of the reactive diluent via transesterification reaction has been followed with 1H NMR analysis of model systems. Dynamic mechanical analysis (DMA) measurements, of free-standing films, showthat the glass transition temperature (Tg) decreases upon addition of the reactive diluent. Both the amount of incorporated reactive diluent and the final film properties are affected by the number and placement of alkene-bonds in the FAME.
