Self-clean aluminium composite sheets

The panel comprises a polyethylene core between two aluminum skin, the LDPE core's thickness and alloy's width can be designed according to customers requirement, the front surface is coated with PVDF paints, the protective film on the top surface can be peeled off. The back sheet is done by anti-corrosive pretreatment or coated with anti-corrosive paints.

The panel comprises a polyethylene core between two aluminum skin, the LDPE core's thickness and alloy's width can be designed according to customers requirement, the front surface is coating with PVDF paints, the protective film on the top surface can be peeled off. The back sheet is done by anti-corrosive pretreatment or coating with anti-corrosive paints. The Nano-PVDF panel is coated another anti-pollution Nano paints based on the PVDF coating layer. This panel not only succeeded to the traditional PVDF coating panel's advantages. But by the high-tech Nano technology ,it have more super advantages in pollution resistance, self-cleaning function, acid resistance and alkaline resistance.

Nanometer introduction:
A Nanometer ( Abbreviation, Nano or NM ) is a unit of spatial measurement. Just like Inches, Feet and Miles, etc., A Nanometer is one billionth of a meter (1nm = 1 x 10-9m) or ( 1nm = 1/1,000,000,000 meter ) , which is equivalent to the length of ten hydrogen atoms. For comparison purposes, The average diameter of a human hair is 350, 000 nanometer, and the average diameter of a red blood cell is 7,500 nanometers. The size of bacteria is approximately 200 to 300 nanometers; a virus is around 100 nanometers. The DNA double helix structure in a cell is roughly 10 nanometers. A nucleic acid is at around 1 nanometer. A Nanometer-sized particle also is smaller than a living cell and can be seen only with the most powerful microscopes available today. Therefore, Nanotechnology was a part of biological changes when life began 300,000 years ago. It is commonly used in Nanotechnology.

According to the advantage of Nanometer, so we apply the Nanotechnology to the Coating for the Aluminum Composite Panel. We call this coating as

Nano-Photocatalysis Coating. This is the separate coating layer above the normal PVDF coating, It’s an additional coating based on high-tech paints, also it is one kind of transparent coating.

Because the particle of Nanometer paints is very small, so any dirty dust will be difficult to stick between particle and particle, also the Nano-Photocatalysis coating have the hydrophilic feature, so the oil and water bilge is very difficult to stay on the surface of Nano coating. Because the particle reach the Nano grade. So the other important feature is the coating layer is transparent, for this which don’t destroy the feature of PVDF coating.


A) May be widly used in gallaies, exhibition, saloons, stores, offices, banks, hotels, restaurants and apartments.

B) An ideal decorative materials for buildings.

C) An ideal outer and inner walls.


1) Direction of Panel:
Metallic and mica coatings have a reflective or pearlescent finish, due to the millions of microscopic aluminum or mica particles suspended in the paint mix. These particles are oriented in the longitudinal direction during the coil coating process. During production, arrows and a production number are printed on the back surface of the panels. Directional arrows are also printed on the strippable protective film. Consequently, it is important when fabricating and installing panels with metallic or mica coatings to take this orientation into account. Panel directionality must be maintained in order to avoid shading differences between adjacent panels and must be taken into account when making the optimization calculations.


2) Protective film: 

The film protects the paint finish during fabrication and installation. It   should, however,be removed as soon as possible after installation of the panel on site, especially in the case of panels   exposed to sunlight and weather. The protective film should only remain temporarily on   the panels. Arrows are printed on the film to indicate the direction of coil-coating   (important for metallic finishes). Opaque film 80 μ thick with ultraviolet barrier is used   on PVDF.


3) Grooving: 

When aluminium-plastic panel is under edge fold construction, it shall be grooving at edge fold     section and it may open V-groove and U-groove, etc. according to edge fold requirement, several typical grooving ways see figure C.l. It shall make use of Special grooving machinery for aluminium-plastic panel to ensure grooving depth is not damage the opposite aluminium material and it shall be left with 0.3 mm thick plastic layer. It may adopt  reinforcing measures as bordered rib, etc. as it is required at grooving section. Unit is mm  4) Lacquer Cleaning Information:



Cleaning Solution:

Cleaning intervals depend on local environmental conditions and the resulting amount of soiling. Surface should be cleaned either manually or with a suitable cleaning device from top to bottom.

Please do not use any abrasive pads on lacquered surfaces. We recommend that the cleaning agent be tried on an unobtrusive part of the object to be cleaned to check whether the surface is affected.

Do not clean hot surface(>40) as the quick drying process may cause blemishes.


Main Procedures of cleaning of Stove-lacquered surface
1.use clean water to wash the lacquered panel surface;
2.use soft cloth which soaked with cleaning agent to wipe the panel surface lightly;
3.use a lot of water to wash away the dirt on the panel surface;
4.check the panel surface carefully, use cleaning agent to clean the remaining dirt area;
5.use a lot of water to wash all panel surface till all panel surface without any remaining cleaning agent.

Note : An increased expenditure of cleaning may be necessary in case of very dirty/soiled area or area which was not cleaned for a long period.  In the case, the time of reaction/agitation or stronger mix/dosage of the cleaning agent may be necessary.  An increased of force during the cleaning process is not recommend because of a high risk of damages (e.g. changed of degree of brightness/gloss)

Please do not use any powerful alkaline cleaning agents such as potassium hydroxide, sodium carbonate or caustic soda, or any powerful acidic products or heavily abrasive scouring agents or lacquer-dissolving cleaning agents.
