What are the reasons for not being able to obtain rust prevention? Alternatives and pretreatment.
What to do when the arrival of rust-proof paint stops. This explains how to ensure rust prevention during pre-treatment and alternative considerations.
The rust-proof paint we were using is out of stock. Simply matching the color with an equivalent product is not enough. ────────────── ■Cause of Occurrence Rust-proof paint is made from resin and anti-corrosion pigments. Both raw materials are in short supply, and shipments of some brands have stopped. ■Truth Even with the same "rust-proof" label, if the resin type changes, the compatibility with the topcoat changes as well. If you only change the primer and leave the topcoat as is, it will peel between the layers. Even if the color is the same, the anti-corrosion performance is not the same. ■Improvement Measures When changing the primer, conduct adhesion tests in combination with the topcoat. The fundamental anti-corrosion can be enhanced through pre-treatment processes such as chemical treatment. Please utilize the materials on anti-corrosion enhancement through pre-treatment.

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.
