  • Patent number: 9389176
    Abstract: The present invention is directed to a device for predicting amount of coarse flakes, such as metallic aluminum flakes present in a coating composition, such as automotive OEM or refinish paint. The device includes measuring flop of a layer of the coating composition applied over a test substrate by using flop prediction device of the present invention. The process is repeated with varying amounts of one or more different types of coarse flakes added to the composition and the flop vs. amount of coarse flakes present in the coating composition is plotted on a graph and then by using a curve fitting equation, a flake amount prediction curve is obtained. By measuring the flop of a wet layer of a target coating composition, the amount of coarse flakes present in the target coating composition can then be predicted by using the flake amount prediction curve. The device is most useful during the manufacture of coating compositions, such as automotive OEM and refinishes paints.
