Pressure relationship like that shown in Fig. 44. 43 Permeability coefficient depending on pressure when the penetrant is highly soluble in a glassy polymer. 44 Permeability coefficient depending on pressure when a highly soluble penetrant plasticizes a glassy polymer. 2 Dependence of Permeability, Diffusion, and Solubility on Temperature e The Arrhenius Equation The Arrhenius equation is a simple, but remarkably accurate, formula for the temperature dependence of the chemical reaction rate constant.

The permeability of a coating or other free films to water vapor is measured by suspending the film of the material across the top of a wide shallow cup that is filled with some water. The cups are sealed so that the only way for water to escape is through the suspended film. , in a desiccator. During the test, vapor passes from the cup through the film specimen into the desiccator in a controlled environment. Weight loss of the cup’s content over a specified period is used to determine the rate of vapor transmission through the film.
