What causes the color of color clear to differ in parts? Film thickness and substrate.
The color clear that enhances the metallic texture has differences in color that directly correspond to the film thickness and the underlying layer. This explains the management of color matching.
Even though it's the same color clear coat, the intensity of the color varies depending on the part. This difference is more noticeable with paint that emphasizes the metallic texture. 【First, please look here】 □ Areas with thicker paint are darker in color → The difference in film thickness directly translates to a difference in color. □ Even with the same film thickness, the color differs by part → This is due to differences in the polishing of the base material and the color of the material. □ Only the corners and edges are lighter in color → Paint does not adhere well to corners, resulting in a thinner film. 【Why does this happen?】 Color clear coat is a transparent coating with color. Since the base material is visible through it, the difference in film thickness and the base material is directly reflected. 【Countermeasures you can implement starting today】 1. Set target values and tolerances for film thickness and measure them. 2. Standardize the polishing method and material lot of the base. 3. Create three color samples with varying film thicknesses to ensure consistency. 【Free Materials】 You can download a guide summarizing how to identify and address painting troubles for free from the related catalog on this page.
