Sites that secured an excess of paint due to supply concerns in spring 2026 should be cautious. Paint that has been stored for a long time may settle or thicken, leading to clumping and color variations.
When I used the paint that I had secured in abundance during spring, it had lumps. The color also looks slightly different from the previous batch. 【What is happening now】 In spring 2026, there were successive shipping restrictions and order suspensions for thinner and solvent-based paints. Is the paint secured at that time still sitting in the warehouse for a long time? 【First, please check here】 □ There is a hard sediment at the bottom of the can → The pigment has settled and solidified □ Even after stirring, particles remain → Some of the paint has started to solidify □ When opening the can, there is a film on the surface → The surface has solidified due to exposure to air 【Countermeasures you can take starting today】 1. Write the arrival date on the can and use them in order of age 2. Check the expiration date indicated by the manufacturer and test the paint before using any that has expired 3. Stir thoroughly before use and strain through a mesh 【Free materials】 You can download a document summarizing the scope of Eiwa Kogei's powder coating services for free from the related catalog on this page.

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.
