What is chameleon coating aluminum sheet
Chameleon color-coated aluminum sheet is made by adding ultra-fine flaky powder to PVDF paint or PE paint, and adding a layer of chameleon coating on the aluminum sheet coated with the base color, so that the formed coating reflects the sunlight and produces different colors from different angles.
Chameleon coating aluminum sheet is coated with a special high-gloss paint, which feels smooth and has a gorgeous and soft color like metal. It makes full use of the reflection, refraction and diffraction between light and matter to transform the wonderful colors in nature, so that the color of the aluminum composite panel decorative surface can present completely different colors with the change of light source and viewing angle.
What is the paint for chameleon coating aluminum sheet panel
Color-changing paint is a special paint that changes color with the help of other substances. The color will change with the change of light and viewing angle.
Classification:temperature-changing paint, ultraviolet light-changing paint, natural light-changing paint at different angles (chameleon paint), etc.
Common alloys and coating thickness
Common alloys
Due to different consumption habits of customers, the alloys commonly used for chameleon coating aluminum sheets are 1100, 1050, 3003, 3004, 3005, 5005, 5052, and even some customers will choose 6061 due to its better strength and formability.
The choice of aluminum alloy mainly depends on the specific requirements and environmental conditions of the project.
For example, high-rise structures or high wind pressure areas tend to choose 3003 aluminum alloy because it provides better rigidity and stability. In low wind pressure areas, such as low-rise buildings, 5052 aluminum alloy may be chosen.
It should be noted that the coating thickness of the fluorocarbon coating formed by the roller coating process is usually thinner than that of the spraying process, which may affect its UV resistance and wind erosion resistance. Therefore, it is very important to choose the right aluminum alloy and coating combination for a specific application.
Coating thickness
The front side adopts a three-coating and three-baking coating process system.
The primer is a high-performance polyurethane paint with matching fluorocarbon with a film thickness of 5-6μm, the intermediate coating system is PVDF (polyvinylidene fluoride), the film thickness is 18-20μm, and the outermost coating system is PVDF (polyvinylidene fluoride) chameleon varnish with a total dry film thickness of 32-35μm; the back coating is a single coating with a total dry film thickness of 5-7μm to ensure the corresponding weather resistance.
How to make chameleon aluminum sheet
The production of chameleon coating aluminum sheet mainly involves a special high-gloss coating that can be perfectly integrated with metal sheets through a high-temperature roller coating process.
Product manufacturing process
- Coating mixing: Add ultra-fine flaky powder to PVDF coating or PE coating to form a chameleon coating, making the surface of the decorative layer gorgeous, while having the excellent performance of fluorocarbon coating or PE coating.
- Sheet coating: After the aluminum sheet is coated with the base color, a layer of chameleon coating is added. This coating reflects the sunlight and produces different colors from different angles.
- Baking and curing: After three coatings and three baking processes of base, middle and surface, the coating and aluminum sheet are more firmly combined and the performance is more stable.
Worthwill’s advantages of chameleon aluminum
Color-changing effect: The surface is colorful, giving people a visual feast
Weather resistance: The weather resistance of this sheet exceeds the national standard requirements and is suitable for various climatic conditions.
Chemical resistance: It has excellent acid and alkali resistance.
Physical properties: The surface hardness and flexibility are higher than similar products, and the wear resistance and impact resistance are also better than general aluminum sheets.
Use of chameleon color coated aluminum sheet
Indoor and outdoor wall decoration
Chameleon coating aluminum sheet is often used in the construction industry, such as curtain walls, ceilings, decorative paintings, etc. It feels smooth and has a gorgeous and soft color like metal. It makes full use of the reflection, refraction and diffraction between light and matter to transform the wonderful colors in nature, so that the color of the decorative surface can show completely different colors with the change of light source and viewing angle.
The surface coating of Worthwill's chameleon aluminum honeycomb Composite Panel for exterior walls uses≥70% fluorocarbon raw materials and pearlescent mica materials. The chameleon aluminum honeycomb composite panel of the interior wall series is more popular with PE coating.
Decoration of advertising background wall
Chameleon coating aluminum sheet is mainly used for outdoor door signs, which means that the middle wood board is omitted, that is, the aluminum sheet is directly fixed to the steel frame. There is no bottom sheet support, so the requirements for aluminum sheet are relatively high, so as to ensure the flatness and firmness of the sign. This method is mainly used for outdoor door signs.
Chameleon color coated aluminum sheet can also be used for billboards, signboards, and entertainment venues. After further pressing and composite molding, it is made into various decorative sheets for decoration in special fields to achieve special decorative effects.
Household appliance panel
Chameleon colorful aluminum sheet has extremely high flatness, and the color and gloss are just right. It is beautiful and attractive, but not too dazzling. At the same time, it can also meet consumers' requirements for health and environmental protection. The antibacterial and chromium-free color-coated sheet reduces bacterial contamination on the surface of home appliances and reduces the harm of chemical substances.
Chameleon coated aluminum sheet also has good corrosion resistance and can cope with moisture and chemicals in environments such as kitchens.
And it can adapt to complex forming processes such as stamping and bending. The coating has excellent adhesion and flexibility to ensure that the coating will not fall off or crack during processing.
