Anoxidall boasts many years of experience in powder coating, a process of aluminum finishing achieved through the use of powder products to coat metal surfaces with different shades of colour. The layer of paint powder adheres to the treated material electrostaticaly, and is then polymerized in an oven at a temperature of about 180 °.
Powder coating is particularly suitable for materials that require an aesthetic and elastic coating, resulting in significant advantages in terms of more homogeneous distribution of the paint and greater durability and resistance over time.
Before the powder coating process, aluminum can be pre-treated in two ways:
The powder coating with oxidation pre-treatment is specially designed for aluminum, a material highly resistant to corrosion by chemical and atmospheric agents, and particularly suitable for marine environments, where exposure to filiform corrosion is greater.
This type of pre-treatment consists in the formation of a specific anodic oxide to anchor successive layers of hot-cured organic powder paint for exteriors. This system combines the high resistance of the anodic layer with a polyester powder paint film (TGIC Free)..
Powder coating with pre-treatment of SEASIDE AA Chromium Free, offers an excellent protection and adhesion base before painting. The hexavalent chromium-free treatment process consists of a greater surface removal of aluminum compared to conventional treatment, with consequent better cleaning from oxides and impurities and greater resistance to corrosion of the painted profile, making it ideal for environments with a strong presence of pollutants (highly industrialized or busy areas).
The reduction of the load of polluting materials arriving at the waste water purifier, the environmental compatibility and the non-harmful chemical bases, make the SEASIDE AA pre-treatment particularly innovative in compliance with environmental regulations and approved by bodies such as Qualicoat and GSB International, for use on architectural aluminum.
To obtain maximum colour resistance and durability, Anoxidall uses Qualicoat class 2 powders, tested and certified according to Qualicoat classification based on the resistance to atmospheric agents of the various paints.
Furthermore, all the powder coatings used are completely non-toxic, to ensure maximum operator safety and minimum environmental impact.
For the powder coating of aluminum, Anoxidall can count on its latest generation and fully automated aspiration system.
A horizontal system in a continuous circle with catenary wire, which allows us to obtain high quality products ever quicker and to guarantee our customers a wide range of colours to choose from.
Anoxidall has always paid great attention to environmental sustainability, constantly developing its production processes to ensure the highest quality and the lowest possible impact on the surrounding environment.
Our processing techniques stop dispersion, avoiding the emission of dust or potentially polluting elements into the atmosphere. In fact, during the painting process, the excess powders that do not adhere to the surface are recovered thanks to the filtering systems and reused in subsequent processing.
