In ZHONGLIAN, powder coating Aluminium profile production is our Best Seller, hundreds colors are available. We can customize the colors based on customers' samples.
The simple steps of the powder coating production process are as follows：On the shelf-pickling-washing-chromizing-washing-drying-off the shelf-on the shelf-spraying-curing-unloading-packaging
Our spray coating has undergone anti-bending test and impact resistance test to detect that the coating has no cracking or falling off.
No particles can stay in the air during the processing, which would allow our profile surface color to be smooth enough and without any particles on the surface. Actually this is a technical problem which can hardly be resolved by other factories. This is also our product advantage as comparing with other profiles with the same color in the market.
Today, we will make a brief on the difference between fluorocarbon coating and powder coating for doors and windows and curtain wall profiles.
Powder Coating
Powder coating raw materials: polyurethane, polyurethane resin, epoxy resin, hydroxyl polyester resin, and epoxy-polyester resin, can be prepared in various colors.
The characteristics of powder coating: spraying equipment is manual, automatic hanging, simple construction, the coating thickness of more than 30 microns, impact resistance, friction resistance, corrosion resistance, weather resistance (the entry "weather resistance" provided by the industry encyclopedia), and so on are good, the coating price is much lower than fluorocarbon.
The biggest weakness of powder coating: is afraid of ultraviolet radiation from the sun, and long-term exposure will cause natural fading. The color difference between the sunny and non-sunny sides of the door and window profiles is obviously after a few years, generally in 2-5 years.
Nowadays, the color aluminum profile on the market is powder coating, which not only increases the color variety of aluminum doors and windows but also enhances corrosion resistance.
Fluorocarbon Coating
Fluorocarbon coating belongs to high-grade coating with a high price, which has a wide application aboard. In recent years, fluorocarbon coating has been widely used in aluminum curtain walls, and door and window materials. Because of its excellent characteristics, more and more attention and favor from the construction industry and users.
Features: with excellent resistance to fading, frost resistance, corrosion resistance to air pollution (acid rain, etc.), UV resistance, crack resistance, and can withstand severe weather environments, the general paint can not do that.
Fluorocarbon spray coating is made of polyvinylidene fluoride resin nCH2CF2 baking (CH2CF2)n(PVDF) as the base material or with aluminum powder as the color material. The chemical structure of fluorocarbon base material is bonded by a fluorine carbonization bond, which is considered the most stable and firm combination. The stability and firmness of the chemical structure make the physical properties of fluorocarbon coatings different from those of general coatings. In addition to the wear resistance in mechanical properties, impact resistance (the entry "impact resistance" is provided by the industry encyclopedia) has excellent performance, especially in harsh climates and environments that show a long-term fading resistance, UV resistance.
As for coating life, the manufacturers of fluorocarbon spray coating guarantee 10 to 15 years but now up to 20 years. American research institutions have tested and compared with fluorocarbon coatings, super coatings, and general coatings: the samples of the coatings were exposed to the hot sunshine in Florida and the harsh environment of wet and salty air for 12 years. It has been proved that the stability and durability of fluorocarbon coatings are 30 percent and 80 percent higher than those of the other two coatings. Fluorocarbon coatings guarantee their use in all kinds of harsh environments.
How to distinguish between fluorocarbon coating and powder coating?
The surface of high-quality fluorocarbon paint is smooth and non-reflective, and an electrostatic powder coating is bright and thick.
Fluorocarbon coated Doors and Windows profile
With its excellent and stable characteristics, fluorocarbon coating has quickly become a new favorite in the aluminum alloy Doors and Windows market. Nowadays, it is mainly used in the curtain wall of various large buildings, aircraft, ships, Doors and Windows of high residential buildings, etc.
