Base ant top coatings for PVD and Sputtering process

What is PVD ?

The "Sputtering" technology is the definitive alternative to the galvanic chroming plating process that, on both metal or plastic, is considered highly damaging for the health.

Powder coating is one of the most flexible procedures in order to physically deposit the “PVD” Vapour and Sputtering.

The PVD processes allow an almost limitless production of coatings for metal or other material surfaces in various combinations.

For what concerns abrasion resistance transition metal carbides and nitrides are produced (for example Titanium and Zirconium).

Not only they present a particular hardness and abrasion resistance but they also allow the use of innovative colours for decorations to be applied on the surface of high quality goods.

The coating material (for example: Titanium or Zirconium) is placed in the vacuum room as cathode in the form of a metallic plate. After having emptied the room Argon process gas is introduced. High voltage is applied and gas is introduced. The Argon positive ions are accelerated on the negative cathod and eject the metal plate atoms, which later descend on the substrates present in the room and condense them.

In the case in which together with the condensation gas a reactive gas as Nitrogen or acetylene are also introduced in the room, the carbide reactive nitride is developped on the substrates.

Various cathods made of different materials may undergo a vacuum coating procedure so to produce multi-layer system.

It is also possible to modify the single layer combination changing the combination of the reactive gases.

The PVD precesses allow an almost limit less coating production for any type of surface.

“Metal-like” coatings with high abrasion an chemical resistance are produced, most of all, by chrome and stainless steel deposition or employing transition-metal carbides and nitrides (Titanium, Zirconium,…).

Not only they present a particular hardness and abrasion resistance but they also allow the use of innovative colours for decorations to be applied on the surface of high quality goods.

PVD and Sputtering Coatings

Tecnocolor attibutes particular attention to all technological innovations and so in the recent years it has studied the coating cycles suitable for any element that can be treated with the PVD technological process and Sputtering.

Nowadays the interest of the industry is particularly oriented towards those types of topcoats that can be obtained by depositing chrome or stainless steel.

For the chrome topcoat Tecnocolor has already set-up base coatings:

 - solvent or water base UV curing for ABS and other plastic materials;

 - solvent or water base UV curing for metals (Alluminium, zamac, etc.) and thermohardening materials;

 - tradditional curing in oven for metals and thermohardening materials.

Besides we produce UV curing coatings for the protection of the various elements applyied by the PVD technology.

Tecnocolor is at your full disposal with its professionals for any demonstrations, researches and samplings.
