What happens when you reduce the drying time for de-oiling in summer.
In summer, it feels like things dry quickly, but in reality, moisture remains. I will explain the risks of shortening the drying time after degreasing.
Because it's summer, drying should be quick. This assumption can lead to pinholes and poor adhesion. Even if it looks dry on the surface, internal moisture can remain at 80 percent humidity, which is 30 percent more than expected. ────────────── ■Cause of Occurrence In summer, the surface appears to dry quickly, leading to a tendency to shorten drying time. However, when humidity is high, moisture remains inside and in crevices even if the surface is dry. ■Truth The appearance of dryness and the actual removal of moisture are two different things. If you proceed with the process based solely on surface judgment, it will manifest as pinholes or poor adhesion in later stages. ■Improvement Measures In summer, do not shorten drying time; instead, extend it according to humidity. If possible, check with a moisture meter and determine drying completion based on numerical values rather than time. Please utilize the materials for managing the degreasing process in summer.

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.
