Water Vapor Diffusion Through Protective Coatings. Part I. A Method of Measuring Water Vapor Permeability of Coating Films by Radioisotope Tracer Technique and its Application

Abstract

A method of measuring the permeability constant and the diffusion rate of water vapor through a polymer film by the radiochemical method is elaborated. It demonstrates that the radiochemical method, as compared to the ASTM Standard Method, is precise, sensitive and rapid. The radiochemical method is also useful in the investigation of other parameters which influence permeability of water vapor.
