Colour coated aluminium coil coating can be divided into polyester coated aluminum coil (PE) and fluorocarbon coated aluminum coil (PVDF). The polyester coating formed by repeatedly baking the surface of aluminum plate can form a continuous solid film with strong adhesion, which has protective and decorative characteristics. It is a kind of UV resistant coating. Polyester resin is a polymer with ester bond in the main chain as monomer, adding alkyd resin. UV absorber can be divided into Matt and specular series according to glossiness. It can give colorful aluminum products rich colors, good glossiness and smoothness, superior texture and hand feeling, and also can increase the sense of hierarchy and three-dimensional. It can protect the objects exposed to the atmosphere and attacked by ultraviolet radiation, wind, rain, frost and snow; due to the effects of temperature difference, freeze-thaw cycle, corrosive gas and microorganism, the coating can play a protective role. Especially suitable for interior decoration and advertising board.
Fluorocarbon coated aluminum roll (PVDF)
Fluorocarbon coating is PVDF resin, which mainly refers to the homopolymer of vinylidene fluoride or the copolymer of vinylidene fluoride and other small amount of vinylidene fluoride monomer. In the chemical structure of fluoroacid base material, fluorine / carbonization bond is used. The stability and firmness of the chemical structure make the physical properties of the fluorocarbon coating different from the general coating. In addition to the mechanical properties of wear resistance, impact resistance has excellent performance, especially in bad weather and environment shows long-term fade resistance, UV resistance. After the film is formed by high temperature baking, the molecular structure of the coating is compact and has super weatherability. The fluorocarbon coating can be divided into traditional fluorocarbon coating and nano fluorocarbon coating according to the surface film-forming structure. In 1965, pennwalt chemical company of the United States first applied fluorocarbon coating to meet the requirements of high-grade indoor and outdoor aluminum coating. The choice of a wide range of colors, the solemn appearance and durability of the United States added luster to many magnificent curtain wall buildings around the world. The coating manufacturer's guarantee for the service life of the coating starts from 10 years, 15 years to more than 20 years. The U.S. research institute has tested and compared the 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 humid and salty air for 12 years. It has been proved that the stability and durability of fluorocarbon coatings are 30 and 80% higher than those of the other two coatings. The fluorocarbon coatings ensure that the coatings can be used in all kinds of harsh environments Use in environment.

It is especially suitable for the decoration and display of public places such as indoor and outdoor decoration, commercial chain, exhibition advertisement, etc.
Characteristics of colour coated aluminium coil:
Smoothness:
There is no compound high temperature indentation on the surface. There is no residual stress on the plate surface and no deformation after shearing.
Decorative:
Painted wood grain, stone grain, realistic physical texture, fresh natural beauty. The pattern is made at will, giving customers a wide range of personality choices, enriching the humanistic connotation of products, and giving people more enjoyment of beauty.
Weatherability:
The paint pattern is made by coating and baking at high temperature, with high gloss retention, good color stability and little color difference change. Polyester paint warranty for 10 years, fluorocarbon paint warranty for more than 20 years.

Mechanical:
High quality aluminum, plastic and adhesive are selected, and advanced composite technology is adopted. The product has the bending and bending strength required by the decorative board. Under the four seasons climate, the change of wind pressure, temperature, humidity and other factors will not cause bending, deformation, expansion and so on.
Environmental protection:
It is resistant to salt, alkali and acid rain corrosion. It will not corrode itself or produce poisonous bacteria. It will not release any toxic gas. It will not cause corrosion of keel and fixed parts, and it is flame retardant. According to the national regulations, it shall not be lower than Class B1.
Colour coated aluminium coil application:
Colour coated aluminium coil has a wide range of colors, which can be added to residential buildings, large commercial outlets or large exhibition centers. Good plasticity and machinability make it an ideal material for various architectural forms. Color coated aluminum coil has provided architects, designers and owners with personalized color space for external walls and ceilings, and is also the most ideal material for architectural modeling. Whether it is a multi-functional large-scale building or a unique and innovative new-style building, the color coated aluminum roll can always meet the different requirements of modern and classical architectural styles, and make the building colorful. Products in electronic appliances, instruments, lighting, packaging, home decoration and many other fields have been applied.
The products are widely used in construction (aluminum plastic board, aluminum honeycomb, roof wave board, fireproof panel, aluminum ceiling, shutter, rolling shutter door, garage door, awning, gutter), electronic and electrical appliances (computer case, electrical panel), lighting, furniture, solar reflector, air conditioning duct, etc.
