AbstractFree films of phenolic varnishes and unpigmented alkyd resins were prepared by mercury amalgamation and photographic paper techniques. The water absorption, water vapor permeation, and mechanical properties of the films were studied using quartz springs, Payne cups, and a tensile testing machine. It is shown that more reliable results for water absorption and permeation are obtained with films from tinfoil. The method of preparation does not affect the tensile strength or elongation of the coatings.
