Fluorocarbon spraying: nch2cf2 baking (CH2CF2) n (PVDF) with polyvinylidene fluoride resin For the base material or with metal aluminum powder for the pigment made of paint, fluorocarbon spraying high price, belongs to high-grade spraying, domestic and foreign technology is more popular, in recent years for windows and doors, curtain wall and other metal surface treatment.
Due to the better effect, long attachment time by the user's attention and favor. Advantages: Excellent anti-fading, anti-frost resistance, anti-pollution (acid rain, etc.) of the corrosive, anti-ultraviolet ability, strong crack resistance and can withstand severe weather conditions.
Fluorocarbon spraying due to the material chemical properties of stable, good adhesion effect, has become a high-grade aluminum alloy window profile processing mainstream technology, is mainly used in aircraft, ships, building curtain wall, high-grade doors and windows. Powder Coating: Raw materials: polyurethane, polyurethane resin, epoxy resin, hydroxy polyester resins and epoxy/polyester resin, can be formulated in a variety of colors.
Advantages: Spraying equipment has a manual, automatic hanging type, simple construction, coating thickness of more than 30 microns, anti-impact, wear-resistant, anti-corrosion, weather resistance, etc. are good, paint price is cheaper than fluorine carbon.
Disadvantage: The sun ultraviolet radiation, long-term exposure will cause natural fading, aluminum plate sun and non-sunny face after a few years, the color difference is obvious, generally 2-5 years will produce significant chromatic aberration.
