Abstract
Permeability of exterior coatings to water vapor is one of the more important properties affecting their performance. Changes in permeability with increasing relative humidity or temperature are also important, not only because they indicate how a coating may behave in practice but also because they give an insight into the molecular stucture. The effects of relative humidity and temperature upon permeation through and the permeability coefficients of clear phenolic and alkyd finishes are studied. Changes caused by each variable are related to the composition of the coatings and the characteristics of the components.
