Selective metalization

Since 1922, the word metallization has been synonymous with surface coatings. Since the invention of this technique, in response to corrosion problems in steel constructions, successful generations of highly respected principles have led to today's expertise in the technology of surface coating. These developments can be attributed to the dissemination of information about metalization and rapid responses to the needs of the industry.

During the joint high-vacuum coating process via evaporation, the metal first melts and then creates a "cloud" of aluminium vapor which is deposited on a polymer surface, resulting in a thin metal film.

In a perfect vacuum condition (10^-4 Torr), the metal molecules will gravitate to the polymer surfaces, without encountering resistance from air or gas particles, so that the polymer is covered with an even layer of metal. Before the high-vacuum coating process can take place, the polymer surfaces have to be leveled and insulated by an initiation layer (varnish) in order to allow the metal layer to be deposited properly and to improve adhesion of the next transparent protective layer (varnish).

To Properly Withinthe metal layer to allowfor bed and the adhesion of the transparent protective layermaking (fe: varnish).

The treatment of the initiation layer undertakes three basic features, enabling higher quality results:

• Aesthetic features
• Insulating function
• Functional interface on the points of the adhesion layer.

The aluminum and the metal layers, both aesthetic and functional qualities. 80% of high-vacuum metallization processes are used for aesthetic purposes, but also thefunctional purposes has increased rapidly, due to a change in galvanic processes,which are currently very costly and extremely dangerous especially for the environment.Recently, multiple cycles low (high vacuum metallization and further formation of multiplemetal layer) developed in various fields such as electronic, electromagnetic reflectionand insulation with excellent results for both aesthetic and functional standpoint.

The treatment of the protective layer of varnish protects the aluminum and metal oxidesat low and represents the final phase coating, which is a highly coherent multiple layerpackage.
