Would you like to create your own original product? We will paint the high-end stainless steel cooler box from YETI that you requested!
Only the exterior of the product was treated. By removing all detachable parts for treatment, we were able to achieve a uniform finish. The exterior included stainless steel and plastic resin components, but we ensured adhesion by performing surface preparation with blasting and applying a special primer that is compatible with both SUS and PP. Although I was concerned about the strength of the cooler box's plate thickness and adjusted the blasting process accordingly, there was absolutely no deformation with this product!
Once the surface preparation was complete, we immediately proceeded to the painting process. We applied a special primer and finished with a black urethane resin in a semi-gloss (30% gloss). The semi-gloss coating can result in color unevenness if too thin and excessive gloss if too thick, making it a challenging paint job, but thanks to the skill of the craftsmen, we achieved a beautiful and uniform semi-gloss finish.
The customer's preference was for a matte black finish; however, a completely matte finish has the drawback of having a rough surface that easily collects dirt and is difficult to clean. Since coolers are often used outdoors, we proposed a semi-gloss finish to ensure they could be used in a clean condition for a long time, and we painted it accordingly.
Stainless steel materials like SUS304, which are said to be difficult to paint, pose no problem for Harada Ironworks.
