Why do stainless steel blisters occur? Basics of moisture management.
Blistering of the coating is caused by moisture and oil. We will explain the specific precautions and measures for stainless steel.
Blisters in the paint film after coating. They often occur months later, making the cause difficult to identify. ────────────── ■ Cause of Occurrence Blisters are a phenomenon where moisture or oil trapped within the paint film expands due to heat or humidity, pushing the film up. Insufficient degreasing and drying are the main causes. ■ The Truth Stainless steel has low thermal conductivity, and if the drying time is insufficient, the surface may dry while moisture remains inside. This residual moisture expands later, manifesting as defects. ■ Improvement Measures Ensure sufficient temperature and time during the drying process. It is also important to reliably remove oil during the degreasing process. Please utilize materials that allow you to review drying conditions.

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.
