Color Index of DAUWIN® Aluminum Frames
DAUWIN® aluminum frames undergo a number of processing techniques on their surface that shield the aluminum against corrosion and, of course, create the look desired by the customer, in order to meet the architectural and aesthetic requirements of the building.
The two basic processing techniques are anodizing and electrostatic (powder) coating.
Anodizing: According to the method of anodizing, a layer of oxide (rust) is created on the aluminum surface, which does not corrode when exposed to the atmosphere, since it is already oxidized, thereby protecting the metal. The corrosion behavior of products subjected to anodizing is extremely good, when the processing is done properly, according to the rules of application and use. However, the potential disadvantages of this method are the mandatory metallic appearance of the aluminum and the restriction of colors.
Electrostatic coating: According to the method of electrostatic (powder) coating, the aluminum surface is coated with a layer of polyester paint. The corrosion protection provided by the electrostatic coating is very good, if it meets all the rules of the production process, implementation and use, while it also offers the possibility of unlimited colors shades. However, the possible negative aspects of the technique relate to the risk of detachment of the two materials, paint and aluminum.
