What causes the silver paint to dull? The arrangement of aluminum pieces and the substrate.
I want to achieve a shine like silver foil, but it ends up looking dull and grayish. This explains how the arrangement of aluminum pieces and the conditions of the base determine the shine of silver paint.
I want to achieve a shine like silver foil, but the finish looks grayish. Don't you feel like it doesn't shine even when you change the angle of view? 【First, look here】 □ The brightness is the same from the front and at an angle → The aluminum particles in the coating are not arranged flat. □ The surface is rough, and the light is blurred → The spray was too far, and dry particles are sitting on top. □ Some areas look dark → In places where it was applied too thickly, the aluminum particles have sunk. 【Why does this happen?】 The silver shine is created when fine aluminum particles in the coating are arranged flat, reflecting light like a mirror. If the spray distance or the amount applied is not right, the aluminum particles can stand up or sink, making it look dull. 【Countermeasures you can take starting today】 1. Determine the spray distance and gun speed using a test panel. 2. Apply thin layers instead of a thick coat at once. 3. Compare the shine samples from the front and at an angle in two directions. 【Free materials】 We have compiled painting menus that include silver and metallic options in the related catalog "What Eiwa Can Do for Metal Coating." You can download it for free from this page.

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.
