Problems solved by technology

Ordinary coatings in the prior art are difficult to meet the requirements. Although general alkyd resin coatings, epoxy resin coatings, and fluorocarbon resin coatings have good heat resistance, they usually can only withstand about 200°C and cannot withstand higher temperatures.
Under high temperature conditions, the adhesion of the above-mentioned coatings will become poor, and there will be dry cracking and peeling phenomena, as well as color changes, which cannot meet the needs of current applications.
