Key properties of coil coating and its detection method
A coil coating is a coating applied to the surface of a coil or film material, usually consisting of polymers, pigments, and additives. They can be applied in many different fields, such as building roofing, insulating materials, רכב, and aviation, among others. Coil coatings have good water resistance, weather resistance and UV resistance, which can improve the service life and performance of materials.
