As a premium powder grade, it’s ingredient in high-end paints for metals. PVDF coating has extremely good performance in gloss and color retention.
Polyvinylidene fluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. It is widely used in metal surface which apply to outdoor environment. Such as tubes, metal sheets, plates, cladding, façade, perforated panels, laser cut panels and also insulator for the premium wire.
Surface treatment of aluminum wall panels
Generally speaking, there are 5 procedure of PVDF. Firstly need pretreated by washing, chromizing, and then coating with fluorine-carbon resin (PVDF coating). PVDF coating is categorized into primer, topcoat, and clearcoat, with polyvinylidene fluoride resin as the main ingredient.
The PVDF coating has excellent corrosion resistance and weather resistance; it can resist acid rain, salt fog, and all kinds of air pollutants; it can also withstands the strong ultraviolet radiation and provides great resistance to hot and cold weather conditions, no color fading and pulverization, and maintain a quite long service life.
PVDF coating has high efficiency and as you can find its application which are exposed to the external weather like the metal framework in buildings that need to retain the color and gloss over a large period of time. So it’s recommended to be used in application for outdoor environment due to it’s premium performance in gloss and color retention. Especially for building projects like metal curtainwall and frameworks and roofing, enveloping, cladding, wall panel.
Using high quality PVDF coating materials from the world’s leading fluorocarbon coating manufacturers such as PPG, DNT, AKZO, NIPPON and so on, provides you plenty of color choices; you can choose color from the color sheet or we can customized the color as per your samples.
