Aluminum profile can be used everywhere. Extruded aluminium profiles created by aluminium extrusion manufacturers without surface treatment have single appearance, which easy to corrosion in the damp or other harsh environments. It is difficult to meet the high decorative and weathering requirements of building materials. In order to improve the decorative effect, enhance the corrosion resistance and prolong the service life, extruded aluminum profiles generally have surface treatment, and the aluminum surface treatment becomes an indispensable important production process in the extruded aluminum profile processing process. PVDF is one of the aluminum profile surface treatments.
The application of architectural coatings in exterior wall decoration is up to 60%. The construction industry is the largest area for coating applications and the largest market for PVDF coatings. PVDF is one type of electrostatic coating and the other type is powder coating.
The PVDF profile is uniform in color, and the PVDF coating with excellent quality has metallic luster, vivid color, and clear 3D appearance. Even if the building is expanded after many years, the old and new colors can still be seamlessly matched. PVDF coating has excellent resistance to fading, anti-blooming, anti-air pollution corrosive(acid rain, etc.), wear-resistant, weather-resistant, anti-aging, anti-ultraviolet ability, strong crack resistance and can withstand harsh weather conditions specialty. The powder coating is afraid of the sun's ultraviolet radiation, relatively weak resistance to fade.
According to the respective characteristics of PVDF coating and powder coating, the general outdoor profiles will basically choose to use PVDF coating. The indoor profiles are mostly powder coating and the concealed parts are also anodized.
Aluminum profile for outdoors, including curtain wall plate, aluminium gusset plate, decorative plate, aluminum outer panel, aluminum grille, etc., should generally be treated with PVDF coating,not only it is prone to fading and surface cracks, especially frequent wind and rain , high wind pressure, strong UV areas, but also it need high-quality surface treatment. For non-outdoor curtain wall profiles, such as curtain wall columns, beams, etc., it generally use powder coating. As for aluminium window profiles, the outdoor part of thermal break profile can be fluorocarbon coated, and the indoor part of thermal break profile is set as powder coating.
Xingfa Project-Bufj Khalifa Uses PVDF Coating Profile
Xingfa Aluminium , the top aluminium profile supplier in China, had set up its five production bases one after another in Yichun Jiangxi of Eastern China, Chengdu Sichuan of South west China, and Qinyang Henan of Central China to produce aluminium profile. Foshan and Nanhai subsidiaries has implemented zero distance strategy that we insist in producing in local, customer in local, serve in local. Xingfa also utilizes its product quality standard and customer service standard, to become a perfect enterprise in this industry.
