The fluororesin has excellent weather resistance, corrosion resistance and stain resistance due to the special chemical structure in the fluororesin, and has a wide application prospect in the field of corrosion resistance due to certain high and low temperature resistance when being made into a normal-temperature cured fluorocarbon coating,
metal corrosion is a phenomenon in which the metal surface is damaged by the chemical or electrochemical action of the environmental medium, and the most effective and common method for preventing corrosion is to apply an anti-corrosion coating on the metal surface to isolate the substrate from the corrosive medium. The corrosion resistance of the coating is mainly reflected in the corrosion resistance of the coating to a corrosive medium and the permeability resistance of the coating to the medium. Therefore, to improve the corrosion resistance of the coating, firstly, the corrosion-resistant resin is selected, and secondly, the corrosion-resistant filler with excellent service performance is used; the anticorrosive fluororesin coating has the advantages of high adhesion, extremely high wear resistance, high-temperature curing and the like, and is widely applied to the field of anticorrosive coatings.
