What are the characteristics of aluminum profiles treated with fluorocarbon coating technology?
Fluoropolymer is a new type of coating based on fluororesin. After a series of process treatment, its stability is better than all coatings, it can resist more pollution corrosion.
1. Good weather resistance
Fluoropolymer contains a kind of f-c bond. The distance between the bonds is more than 0.126nm, which is the shortest bond among all Chemical bond. The bond can reach 460kj/mol, which is generally difficult to break. The f-c bond has good weather resistance can withstand strong ultraviolet radiation for a long time. Even in harsh outdoor environments, the appearance can be maintained for 20 years without brown, which can extend the life of industrial aluminum products.
2. Strong corrosion resistance
In order to increase the adhesion between surface coatings metal coatings improve the impermeability of the coating surface, a layer of primer with a thickness of 5-10m is first applied to the industrial aluminum substrate surface, then a thick layer of paint is applied to further protect the coating acid rain, air pollution, ultraviolet radiation. The thickness of the surface coating can reach 30m; Finally, apply a layer of coating with a thickness of 5-10m, mainly used to protect surface coatings, improve anti-corrosion ability, enhance the color of the coating surface, make the coating color uniform present different colors. The total thickness of the three layers of paint, including the bottom coating, surface coating, coating, can reach 40-60 μ m. it can be thickened according to the needs of industrial aluminum profiles, so the insulation corrosion resistance of the coating are very high.
3. Easy to clean
The contact angle between the coating water is called the contact angle. When the contact angle is less than 90, the coating surface has hydrophilicity is easy to wet; When the contact angle is greater than 90, the coating surface is hydrophobic easy to wet. The fluorocarbon coating surface can reach 110, the fluorocarbon coating surface is smooth. The coating surface is very smooth, the water adhesion on the coating surface is very small, which can move freely without wetting is easy to clean.
4. Good temperature resistance
Fluorocarbon coatings have excellent temperature resistance. Ptfe coatings can withstand 250 ℃ even 300 ℃ for a long time, while other coatings can be used at 50 ℃, making industrial aluminum products have good weather resistance.
5. Easy to process
Fluoropolymer has very good adhesion many processing methods. It can be sprayed, brushed roller coated. It can also be mixed into various desired colors, such as metal color, pearlescent color other colors, according to design requirements, to meet the needs of more high-end industrial aluminum profile application customers, with better decoration effect.
