Abstract: A solvent borne brushable coating composition having improved sag resistance and process for using the same are provided. The composition includes a crosslinkable component having one or more polymers having two or more crosslinkable groups a crosslinking component comprising one or more crosslinking agents having crosslinking groups; and a sag control agent of polyurea in drying oil. When a layer a pot mix resulting from mixing of the crosslinkable and crosslinking components is brush applied over a substrate, it has high sag resistance, low brush drag while providing desired coating properties, such as high gloss and rapid cure even under ambient conditions. The solvent borne brushable coating compositions is well suited for use in automotive refinish applications as well as direct-to-metal industrial applications, such as construction and transportation equipment.

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.

Abstract: 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.

Abstract: A coating composition comprises high oleic oil, wherein the high oleic oil comprises C18:1 fatty acids in a range of from about 60% to 100% of the fatty acid moieties in the high oleic oil and a combination of C18:2 and C18:3 fatty acids in a range of from 0% to about 10% of the fatty acid moieties in the high oleic oil, percentage based on the total fatty acid moieties in the high oleic oil. The disclosure is further directed to a coating composition comprising the high oleic oil produced from bio-resources, such as soybeans. The coating composition can have low VOC (volatile organic compounds) and can produce a coating layer having good hardness, better appearance and improved adhesion.
