The influence of surface properties on the surface energy of a variety of tinplate substrates is examined using contact angle analysis. A comparison of the Good-Girifalco and Owens Wendt method is made highlighting the difference in calculated surface energy between the techniques. This is found to be due to the ratio of the polar and disperse components of the substrate and test liquid. Good correlation between techniques is seen when this ratio is at unison. The Owens Wendt method is used to show the effect of surface variables on surface energy. The relationship between surface energy and surface properties is used to suggest substrate combinations that would be susceptible to lacquer dewetting. Increased levels of roughness, tin coating and chromium passivation are seen to decrease the surface energy of tinplate. Tinplate substrates were lacquered and the coating quality tested. The influence of the lacquer’s properties such as surface energy and viscosity coating performance are also discussed.
