Reports the effects of composition and curing temperature on the film properties of three water reducible enamels prepared from palm stearin alkyds. The properties studied were hardness, flexibility, and adhesion. While all the formulations exhibit excellent adhesion, generally increasing the melamine content and curing temperature can increase the hardness but reduce the resistance to cracking and deformation of the coating. Applies Fourier transform infra-red spectroscopy (FTIR) to the study of the curing reactions. Finds that FTIR is able to identify the predominant cross-linking reactions.
