Abstract
Internal stress developed in a solvent-cast thermoplastic coating was measured by using the substrate as a cantilever. Precautions necessary to obtain accurate experimental results are presented, as well as a comparison of two methods of differing complexity used for their analysis. Residual internal stress was found to be large and independent of dried coating thickness and initial solution concentration. The stress distribution in the coating and the drying kinetics are discussed in the light of these results, as are some practical implications of the magnitude of the stress.
