Prepainted Aluminum Coils

Colored aluminum panels are widely used because of their light weight, bright colors, easy processing and forming, and no rust. Including;

(1) Building decoration field: manufacturing roof panels - curtain wall panels - interior wall decorative panels - ceiling panels - honeycomb panels - thermal insulation panels - roller shutters - blinds, etc.

(2) Food encapsulation field: manufacturing pressure-free food cans - can lids - bottle caps - pull rings - food boxes.

(3) In the field of electronic and electrical appliances: manufacturing air-conditioner panels, washing machine panels, refrigerator panels, cabinet panels.

(4) Transportation field: Manufacture of van shells and inner walls, train body panels, ship interior panels, traffic facility signboards, advertising panels, bags, etc.

Differences between Prepainted Aluminum Coil and Prepainted Steel Coil

Polyester coating (PE)

It is a kind of anti-UV ultraviolet coating. The polyester resin is a polymer containing an ester bond in the main chain as a monomer. Ton acid resin is added. The ultraviolet absorber can be divided into matt and high gloss series according to the gloss. Especially suitable for interior decoration and advertisingcoils.

Fluorocarbon coating (PVDF)

It is made by mixing fluorocarbon resin with fluoroalkene as the basic monomer, pigment, alcohol ester solvent and additives. After baking at high temperature to form a film, the molecular structure in the coating is tight, and it has super weather resistance. Fluorocarbon coatings can be divided into traditional fluorocarbon and nano-fluorocarbon coatings according to the surface film-forming structure. Especially suitable for decoration and display of indoor and outdoor decoration, commercial chains, exhibition advertisements in public places.

Coating thickness: PVDF (fluorocarbon)≥25micronPOLYESTER(polyester)≥18micron；

Glossiness: 10-90%；

Coating hardness: greater than 2H；

Adhesion: not less than level 1；

Impact resistance: 50kg/cm, without peeling paint and no cracks. The color of Polyester can be used for 20 months, while fluorocarbon can be used for 30 months without discoloration.

The Characteristic of Color Coated Aluminum Coil

(1) Flatness: No composite high-temperature indentation on the surface. There is no residual stress on thecoil surface, and it will not deform after shearing.

(2) Decorative: Coated with wood grain and stone grain, it has a realistic sense of real material and a fresh natural beauty. The patterns are made at will, giving customers a wide range of personality choices, which can enrich the humanistic connotation of products and give people more beautiful enjoyment.

(3) Weather resistance: The paint pattern made by coating and baking at high temperatures has high gloss retention, good color stability, and minimal change in color difference. The polyester paint is guaranteed for 10 months and the fluorocarbon paint is guaranteed for more than 20 months.

(4) Mechanical: The use of high-quality aluminum, plastics, and adhesives, using advanced composite technology. The product has the bending and bending strength required by the decorativecoil. In the four seasons, the changes in wind pressure, temperature, humidity, and other factors will not cause bending, deformation, and expansion.

(5) Environmental protection: Resistant to salt and alkali acid rain corrosion, it will not corrode and produce poisonous bacteria, does not release any toxic gas, does not cause corrosion of keel and fixed parts.

(6) Flame retardancy: not less than B1 level according to national regulations.
