Evaluation of Architectural Coatings II. Part A: Interior Wall Enamels; Sealing Qualities of Interior Wall Primers. Volume I

摘要

Part A of this report presents the results of a project to evaluate the performance of recently developed water-based and low-solvent interior wall enamels and primers to determine if these products have properties equivalent to the conventional high-solvent products which are now used for the same purpose. The overall performance of water-based and high-solids interior enamels, as a group, was found to be inferior to the conventional enamels. However, two of the water-based enamels and one high-solids enamel exhibited above average performance overall with no serious deficiencies. The test results show that water-based and high-solids enamels can be developed which can readily compete with conventional enamels. However, further work is required to overcome their present deficiencies as a group. Water based primers were tested for their ability to seal water-soluble stains and were found to be ineffective. On the other hand, they were more effective than conventional primers in sealing oil and grease-type stains.
