Notes:
The storage modulus, loss modulus, loss tangent (tanδ), stress and strain have beendetermined for painted steel specimens by dynamic mechanical analysis (DMA) operated in DualCantilever mode. Analysis of the composite system enabled the elastic modulus of the paint layer tobe calculated and the result can be useful to analyze the mechanical properties of the coil coating.The calculation was found to be very sensitive to the geometry (especially thickness of the substrateand coating) and properties of the substrate and coating, leading to considerable variability in thecalculated coating modulus. The DMA method was successful in detecting the glass transitiontemperature (Tg) as a peak in the tanδ curve. The value of Tg is sensitive to the preparationconditions (e.g. curing temperature) and composition of the paint. The results show that DMA inDual Cantilever can be useful as a characterization tool for painted steel
