What causes outdoor paint to fade quickly? The difference between general-purpose paint and resin.
The paint on outdoor parts fades to a whitish color faster than expected. The cause may be the type of resin in the paint. An explanation of the differences between general-purpose paint and high-performance paint.
The paint on parts placed outdoors turns white faster than expected. When touched, a white powder sticks to the hand. The color appears lighter. 【First, please look here】 □ Only the sunlit surfaces fade → Deterioration due to ultraviolet rays □ White powder sticks to the hand → Chalking as the surface of the paint film decomposes □ The same paint as used indoors is being used 【Why does this happen?】 The lifespan of the paint film varies greatly depending on the type of resin used to create it, rather than the color components. General-purpose paints excel in price and ease of application, but some are weak against outdoor ultraviolet rays. High-performance paints designed for outdoor use utilize resins that are strong against ultraviolet rays, maintaining color and gloss for a longer time. 【Countermeasures you can take starting today】 1. Inform the painting contractor whether it is for outdoor or indoor use and if it will be exposed to sunlight. 2. Include not only color but also the type of resin as criteria for selecting paint. 3. Compare the total costs of general-purpose and high-performance options, including repainting or replacement costs. 【Free materials】 Choosing paint suitable for your application is introduced in the materials for "Baked Coating Services."

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.
