Chipping caused by flying stones and other factors. This explains measures against insufficient film thickness and poor adhesion.
Chipping of the paint film occurs due to flying stones while driving. Chipping is a defect related to both film thickness and adhesion strength. ────────────── ■ Cause of Occurrence Chipping is a defect where the paint film partially peels off due to impact. If there is insufficient film thickness or poor adhesion to the substrate, resistance to impact decreases. ■ Truth Stainless steel has difficulty achieving adhesion due to the influence of the passive film, and in the case of thin films, it becomes particularly vulnerable to impact. If the substrate treatment is inadequate, this tendency is exacerbated. ■ Improvement Measures Ensure proper film thickness and avoid extreme thin films. Increase adhesion strength with blast treatment and specialized primers. Utilize documents that enhance impact resistance specifications.

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.
