AbstractThe relations between composition and the water absorption, water vapor permeability, tensile strength and elongation of unpigmented phenolic and alkyd films are reviewed. Single and multiple regressions of the different properties on durability ratings of the materials exposed to natural weathering on red cedar panels are calculated to establish their relative importance in durability. It is shown that the durability of clear phenolics and alkyds can be predicted quite well from water absorption and permeability properties. Tensile strength of phenolics and mechanical properties of alkyds are of less importance.
