Application Note 19
Effect of Saline on Epoxy Resin Paint run in Tension Geometry
The use of DMA for the analysis of the a (Tg) relaxation of epoxy resin paint samples will be demonstrated. The resin used for these experiments was used as a corrosion inhibiting coating for marine applications. Samples were prepared and run as received, soaked in saline solution for 7 days and totally immersed during the measurement.
Application Note 20
α and β Relaxations of PMMA and Calculation of the Activation Energy
The use of DMA for the analysis of the α (Tg) and β relaxations of PMMA will be shown in this note. All relaxations are frequency dependant and the results of a multi frequency experiment show clear events for both the α and the β relaxations. The activation energy of both relaxations will be calculated using the Arrhenius equation.
