EVALUATION OF INTERIOR AND EXTERIOR LATEX PAINTS
A search for better latex paints is being made. Exposure tests of twenty latex paints on concrete and wood are in progress. With the development of X-ray techniques for the measurement by diffraction or fluorescence of the thickness of thin films of material, there is the possibility that thin films of paints may be the basis for accelerated outdoor-exposure durability tests. This is being investigated. A rapid disappearance of calcium carbonate and of zinc oxide from such thin films of paint has been demonstrated. Results indicate that zinc is still present but evidently in another form.
