Application Note

Effect of Saline on Epoxy Resin Paint Run in Tension Geometry

Dynamic Mechanical Analysis (DMA) is one of the most appropriate methods to investigate relaxation events. The glass transition (Tg) is a key process in any material but is especially important for paint materials. The mechanical properties of paint are dependent on the temperature that the paint is exposed to during its lifetime. For marine applications, the influence of salt water (saline solution) can have an effect on the Tg and this needs to be understood and quantified. Epoxy resin paint can be applied to an inert surface and, once cured, be peeled off to produce a film. In this application note, the paint film is run in tension geometry in the DMA 8000.
