[China Aluminum Network] When producing two-color aluminum profiles, it's necessary to apply two different colors during the painting process. These two colors usually consist of a light and a dark shade. Before starting the spraying, it's essential to determine the order in which the colors will be applied. The sequence can significantly affect the final result. If the light color is sprayed first and then the dark color, the light-colored coating will go through two baking cycles. This may cause the light color to change color due to heat exposure. On the other hand, if the dark color is applied first and then the light color, the light paint may not fully cover the dark layer underneath. In such cases, the film thickness of the light color needs to be increased to ensure good coverage. However, increasing the film thickness too much can lead to issues like film cracking or uneven appearance. Therefore, in actual production, it's generally recommended to use a combination of shallow and deep color shades to achieve better results and avoid common painting problems.
