From 9 by 11 October of this, 2018, year in Dusseldorf, Germany, the next world Congress ALUMINUM 2018. One of the important topics on the agenda is the latest advances in the decorative and protective treatment of aluminum surfaces..

Processing the aluminum surface
Aluminum owes its success as a material, not least its universal ability to process its surface. The surface of aluminum may be plastic, anodized or even just well machined. Aluminum is easy to process, easily connects to other materials and easily takes the most complex forms.
Thanks to its natural oxide coating, aluminum is highly resistant to external influences even without additional coating.. Depending on application, functions or optical requirements aluminum can receive various colors, design and texture using industrial surface treatments. The chemical composition of aluminum alloys also affects the appearance of its machined surface - this is also taken into account when developing an aluminum product.
Anodized aluminum: sophistication and nobility
Along with powder coating, the main surface treatment of aluminum is anodizing. Anodizing aluminum is also called electrolytic oxidation of aluminum.. During this electrochemical process, the aluminum surface turns into an oxide layer, which has very small, microscopic pores and very high hardness. Compared to the natural oxide layer, this anode coating is hundreds of times harder, and its thickness can be set with great accuracy. This gives aluminum parts and products high wear and corrosion resistance., which extends many times the possibilities of industrial use of aluminum.
Additional technological processes make it possible to obtain colored anode coatings. At the same time, the characteristic “metallic” appearance of aluminum is retained.. This property of aluminum is highly regarded in these market segments., as it gives it a “classic look”, and to designers, constructors, architects and product developers – wide field for creativity.
New aluminum surface finishes
Leading companies, which produce anodized aluminum, provide high quality anode coatings and are constantly busy expanding the functional properties of these oxide coatings so, to find all new markets. In collaboration with chemical manufacturers, they develop wear-resistant dyes., which do not contain heavy metals or substances harmful to the environment. Strict quality control guarantees high resistance to fading under the influence of sunlight and high resistance to weather and climatic influences. Therefore, the attractive appearance of aluminum remains for many years both inside the building, so outside of him.
Endless color choices
For those customers, which does not suit the natural surface of aluminum, an inexhaustible variety of coating colors is offered, like liquid, and powder. Designers and developers have at their disposal the entire range of RAL color tones, as well as additional metal coatings. Depending on the operating conditions of the aluminum material or product, aluminum surface treatment companies are able to offer such coatings, for which severe weather conditions and ultraviolet radiation are fearless. To ensure long-term adhesion of coatings, thorough chemical preparation of the painted aluminum surface is carried out. It also provides surface corrosion resistance..
Relatively new are the so-called photo-decorative coatings. As a result of this multi-stage technology, photorealistic drawings and patterns are created on the surface of aluminum.. Moreover, special powder coatings are often used as the basis, and then color photomotives are applied. Depending on the technology used, the resulting aluminum surface may have a special pleasant tactile texture. The last technological operation is heating in a furnace to a temperature 200 oC. Then applied to the surface of the paint migrates from the surface into the powder coating.
Aluminum experts consider, that the technical advantages and possibilities of personal design open up wide opportunities for these technologies to spread aluminum to new consumer markets. Aluminium alloys, painted by these new technologies, can easily imitate the appearance and tactile texture of wood, steel and glass.
Removal of coatings for aluminum recycling
After that, how coated aluminum products reach their end of life, they are easy to remove from the surface of aluminum. Aircraft coatings are an example: they are often removed and repainted to suit new designs..
New technologies for removing coatings from the surface of aluminum make processing of scrap aluminum easier. Recycled aluminum returns again as new aluminum products.
Pavilion: Surface aluminum
At the Congress ALUMINUM 2018 as previously, a special exhibition area for aluminum surface treatment technologies is provided. More 20 companies will present their achievements in the Hall 12. These will be aluminum painting and anodizing companies, chemical companies and equipment manufacturing companies.
Aluminum Surface Finishing Forum
In Congress with 9 by 11 October 2018 year will host a forum on aluminum surface treatment. Speakers will be leading employees of well-known companies., including, such as GSB and Allufinish.
