The transparency of red and yellow is not solely due to the lack of hiding power in the paint. We will reconsider the undercoating design and film thickness.
When painting with red or yellow, the base layer shows through. Are you increasing the number of coats and labor hours unnecessarily? ────────────── ■Cause of Occurrence Poor hiding occurs when colors with low pigment hiding power do not reach the required film thickness. Red, yellow, and orange colors require approximately 1.5 times the film thickness needed for white or black for adequate hiding. ■Truth Relying on multiple coats to solve the issue can lead to new problems such as drips and chipping due to excessive film thickness. The essence lies not in the topcoat but in the color design of the primer. ■Improvement Measures Change the primer to a gray or similar color that is closer to the final color, and reduce the thickness of the topcoat. Ensure that color variations in the material are made uniform during the pre-treatment stage. Please utilize the recommended film thickness and primer design materials for each color.

Company information
We are not just a "subcontracted painting factory." Established in 1958, our company has a foundation of painting technology and also specializes in chemical treatment, stripping, and cleaning, functioning as the "external surface treatment department" in your organizational chart. Based on our philosophy of "preparation is eight-tenths of the work," we emphasize participation from the "upstream process" before the drawings are finalized. We conduct test painting on a wide range of metals and difficult materials, and we produce the entire process from assembly, packaging, to delivery, thereby reducing your management workload. Additionally, by being able to perform zinc phosphate treatment in-house, we achieve stable painting quality. Furthermore, our micro-heating stripping technology, which does not use chemicals, maintains the electrical state of the "jigs (hangers)" that influence painting quality. Our approach of "pre-treatment determines painting quality" ensures the stability of the paint film during mass production. Rather than simply "applying specified standards," we work backwards to achieve optimal painting specifications and prevent scratches during transportation, sparing no effort in thorough discussions from the outset. This diligent preparation is the shortest path to preventing rework and minimizing total costs. From the development stage, please utilize the expertise of our specialists as part of your production line.
