Does anyone know that UV spraying is not good and how to deal with it?

More defects of spraying UV paint are gray spots and pinholes on UV paint, which are directly scrapped in some industries. However, for the workpieces with repair value, it is very good to use UV repair water to repair and rework, which will save and improve the cost and yield of UV spraying.

Jingchuan UV remediation water is composed of polymers with high polymer interface, which is environmentally friendly and has low VOC emission. Different repair schemes can be carried out for different UV coatings, and the reworked UV topcoat will not have false adhesion. At the same time, Jingchuan UV repair water has excellent covering effect, and the overall paint film thickness has not increased significantly after repainting. Through RoHS test, it does not contain heavy metals and other substances.

How to use ultraviolet rays to repair water;

1. polish the defective products.

2. Clean the surface.

3. Spray UV repair water and dry it naturally for 1-2 minutes.

4. spraying UV varnish, IR leveling and UV curing.

UV rework has played a great role in the field of automobile parts or electronic products. Typical cases include motorcycle parts and mice. After general UV spraying, the product has high surface color and strong decorative effect. If scrapped, the production cost will increase, and the treatment of defective products is also a big problem. Jingchuan uses UV remediation water to reduce the cost and efficiency of production and extend the value of products through remediation.
