  • Patent number: 6538725
    Abstract: The present invention provides a method for quantifying structural defects of a coating composition on a given substrate, where certain structural defect-inducing tests are performed. In this method, a coating formulation is doped with a colorimetric or luminescent material. Concentration of the material depends on the quantum efficiency, excitation and emission wavelengths, and employed detection techniques, and can range from about 1 fM to about 1 mM. Before, during and/or after such tests, the coating is illuminated with a wavelength of radiation at which the reflected or transmitted color or emitted luminescence of the material in the coating is detectable with an optical detector or by visual inspection. In this fashion, the percentage of failure of the coating can be quantified as well as the level of interdiffusion of coating into substrate or substrate into coating. The method of the invention is thus particularly well-suited for the combinatorial analysis of an array of coating samples.

  • Patent number: 6460417
    Abstract: This invention relates to methods for testing elongation and cracking of coating arrays. The method includes simultaneously applying an elongating force to each of a plurality of coatings, and monitoring the coating integrity including cracks and thickness decrease in each coating. A relative performance characteristic of each coating is then determined based on a correlation between a detected crack and/or thickness decrease in the coating, and the corresponding elongating force.
