Development of aluminum coating technology

The great success of aluminum materials is attributed to universal surface design. Whether it's coated with plastics, anodized or machined: light metals are universally applicable and have become an integral part of many technologies and daily life. It is easy to deform, suitable and easy to use. Due to its natural oxide skin, aluminum has a high resistance to external influences even without further coating. Through the surface treatment available in industry, materials can change in color design and structure according to application, function or optical requirements.

A noble and valuable appearance

In addition to today's plastic based coating, anodizing. Also known as the anodizing process (electrolytic oxidation of aluminum), it is one of the most common processes. In this case, the surface of aluminum is converted into oxide layer in the electrochemical process, which is very fine pore and hard. Compared with the natural oxide layer, it is more than 100 times stronger and can be defined according to its thickness. It makes the products wear-resistant and corrosion-resistant, and extends the technical application of aluminum for many times.

Color design is possible even through other processes. Despite the coloring, the characteristic metal appearance of light metals still exists. In many target markets, this effect is highly valued because the noble appearance of metal leaves creative space for designers, architects and product developers. Anodizing company ensures the highest quality coating, and constantly strive to expand the function of the oxide layer to serve the new market. Together with the necessary chemical manufacturers, they have developed long-term sustainable dyes that do not contain heavy metals or environmental toxins. Strict quality control ensures excellent light and weather resistance,

Infinite colors

Anyone who doesn't pay attention to the natural surface of aluminum can rely on an inexhaustible variety of colors, thanks to the plastic coating. Whether it's powder paint or wet paint: designers and developers can use all ral colors or metal paint, and of course create special colors. According to different applications, refineries can provide appropriate coating formulations to eliminate adverse factors such as weathering and UV radiation. The rich experience and professional knowledge of processing companies are the foundation of many markets. In order to ensure the long-term adhesion of the coating, it is necessary to use coordinated work steps for pretreatment. In addition, this pretreatment ensures that the surface is free from corrosion.

Relatively new is the so-called decorative coating. In a multi-step process, photo realistic patterns and any pattern can be applied to metal. In general, a special powder coating is applied based on the basic tone and the color pattern is completed in the second step. According to the technology used, the result is a decoration with a touch able texture. Apply the components to the required decorative film and heat to 200 ℃. The ink diffuses from the film to the powder coating.

Experts believe that through structural advantages and personalized design of components, new applications can be developed for aluminum. Aluminum coated in this way can be used as needed and has the appearance of wood, steel or glass.

Paint stripping and recycling

If coated parts are out of date decades later, they can be easily peeled off or even recoated. For example, airplanes: they are often peeled off in a short time, and then new decorations are used again on the road.

Surfaces play little role in light metal recycling: current processes can be used to separate all coatings, so aluminium can be used to create new applications.

Aluminium 2018 show

In 2018, aluminum once again used its exhibition area for surface treatment. More than 20 companies have appeared in hall 12 as part of the competence center surface technology, where spray and anodizing agents, chemical companies and factory manufacturers will present their solutions.
