The raw materials of powder spray paint are polyurethane, polyurethane resin, ring resin, hydroxyl polyester resin, and ring polyester resin, which can be adjusted to prepare a variety of colors. The spraying equipment can be manual or automatic hanging type, and the construction is relatively simple. The coating thickness is more than 30 microns, and the impact resistance, abrasion resistance, corrosion resistance, and weather resistance are all good.
However, the biggest weakness is that it is afraid of the sun's ultraviolet rays. Long-term exposure will cause natural fading. There will be a color difference between the sunny side and the non-sunny side after a few years. Generally, there will be an obvious color difference in 2-5 years.
Fluorocarbon spray coating is a coating made of polyvinylidene fluoride resin nCH2CF2 barbecue (CH2CF2)n(PVDF) as the base material or with metal aluminum powder as the color material. The chemical structure of fluorocarbon binders is combined with fluorine/carbon bonds. The combination of this structure with short bonds and hydrogen ions is the most stable and firm combination. The stability and firmness of the chemical structure make the physical properties of fluorocarbon coatings different from general coatings. In addition to excellent mechanical properties such as abrasion resistance and impact resistance, it shows long-term fading resistance and UV resistance, especially in harsh climates and environments.
Fluorocarbon spraying is high-grade spraying at a high price. It has excellent resistance to fading, frost resistance, corrosion resistance to atmospheric pollution (acid rain, etc.), strong UV resistance, strong crack resistance, and can withstand harsh weather environments. It is beyond the reach of ordinary coatings. Due to its excellent characteristics, it is widely valued and welcomed by the construction industry and users.
