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 had both 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 SUS and PP. We were concerned about the strength of the cooler box's thickness and adjusted our blasting process accordingly, but there was absolutely no deformation with this product!
Once the surface preparation was completed, 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) finish. The semi-gloss black coating can show color unevenness if applied too thinly and can become glossy if applied too thickly, making it a challenging paint job, but the skill of the craftsman resulted in a beautifully 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 textured 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 remain in good 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.
