Patent number: 9389176Abstract: 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.Type: GrantFiled: February 21, 2013Date of Patent: July 12, 2016Assignee: salesforce.com, inc.Inventors: Anthony Moy, Rajesh Gopalan Saliya, Ayumu Yokoyama

Patent number: 9025153Abstract: The process includes measuring flops of a layer of the coating composition applied over a test substrate of a mottling prediction device of the present invention at the start and then after a desired time interval. A delta flop is determined by subtracting from the flop at the start from that after the desired time interval and a degree of mottling of a coating resulting from the layer is visually assessed. The process is repeated with varying amounts of one or more rheology additives added to the composition and the degree of mottling vs. delta flop is plotted on a graph and then by using a curve fitting equation, a mottling prediction curve is obtained. By measuring the delta flop of a wet layer of a target coating composition, the degree of mottling in the target coating composition can then be predicted by using the mottling prediction curve.Type: GrantFiled: November 6, 2012Date of Patent: May 5, 2015Assignee: Axalta Coating Systems IP Co., LLCInventors: Ayumu Yokoyama, Rajesh Gopalan Saliya, Anthony Moy, Allan Blase Joseph Rodrigues
