Problems solved by technology

[0002] For conventional light anti-corrosion coatings, the life of the coating film is relatively short, and the service life of the coating film can be extended by recoating
Since light anti-corrosion coatings generally use oily or alkyd products, only similar products can be used for recoating. If epoxy, polyurethane or fluorocarbon heavy-duty anti-corrosion coatings are used for recoating, the problem of bottoming will occur
