20130141713 | Process For Predicting Metallic Gloss Of Coating Resulting From Coating Compositions By Wet Color Measurement - The present invention is directed to a process for controlling the metallic gloss of a coating resulting from a coating composition, such as automotive OEM or refinish paint, that contains flakes, such as metallic aluminum flakes. Thus, by adjusting the amount of flattener added to the coating composition, the gloss of a coating resulting therefrom can be controlled from glossy to flat (matte) finish. The process includes measuring reflectance (L-value) of a layer of the coating composition applied over a test substrate by using gloss prediction device of the present invention. The metallic gloss of a coating resulting from the layer is then measured. The process is repeated with varying amounts of one or more flatteners added to the composition and the metallic gloss vs. reflectance is plotted on a graph. Then by means of a curve fitting equation, a metallic gloss prediction curve is plotted. By measuring the reflectance of a wet layer of a target coating composition, the metallic gloss that would be produced by a coating from that target coating composition can then be predicted by using the gloss prediction curve. The process is most useful during the manufacture of coating compositions, such as automotive OEM and refinishes paints. | 06-06-2013 |
20130141724 | Process For Predicting Tint Strength Of Coating Compositions By Wet Color Measurement - The present invention is directed to a process for predicting the tint strength of a pigmented coating composition, such as automotive OEM or refinish paint, on a real time basis while it is being made. The tint strength of a coating resulting from a layer, obtained by adding a reference binder to the coating composition, is measured. The process is repeated by subjecting the coating compositions to successive grinding intervals. The tint strength vs. reflectance is plotted on a graph and then by using a curve fitting equation, a tint strength prediction curve is obtained. By measuring the reflectance of a wet layer of a target coating composition, the tint strength of that target coating composition can then be predicted by using the tint strength prediction curve. The process is most useful during the manufacture of coating compositions, such as automotive OEM and refinishes paints. | 06-06-2013 |
20130141727 | Process For Predicting Degree Of Mottling In Coating Compositions By Wet Color Measurement - 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. | 06-06-2013 |
