Blister defects may be caused by insufficient chemical treatment. I will explain the importance of adhesion and corrosion resistance.
In blister prevention, it is important to check not only the paint and curing conditions but also the chemical treatment process. If the chemical film is not sufficiently formed, the adhesion between the coating and the material decreases, making it easier for moisture and oxygen to penetrate. As a result, corrosion progresses inside the coating, leading to blistering and peeling. Since the chemical film is difficult to see, managing the concentration of the treatment solution and the treatment time is key to ensuring quality stability.

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.
