hello, fluorocarbon paints are classified according to their uses: fluorocarbon paints for exterior walls, fluorocarbon paints for aluminum, fluorocarbon paints for metal, fluorocarbon paints for steel structures, etc. Distinguish according to industry standards: national standard products and non-national standard products. The metal fluorocarbon paint you mentioned, I don't know if Party A has any specific indicators such as age and fluorine content. The price of national standard products is between 121-181/kg (the price varies according to different colors, and the price varies from low to high, and the color varies from light to deep). 3-5 square meters can be sprayed per kg (the spraying area is affected by objective factors according to the construction process, environment and workers' proficiency). The warranty period is over 15 years, and the price of national standard products is 81-1. Spraying area is the same as above. The warranty period is 7-8 years. This answer is not satisfactory. You can also call Runhao Fluorocarbon Materials Co., Ltd. and we will give you a detailed answer.
