Abstract
This presentation shows a different approach to non electroplating coatings on plastic and non ferrous metal substrates. The metalized coating is done by Physical Vapour Deposition (PVD) sputtering, batch or in-line line, along with zero VOC’s UV curable basecoats.
Chrome plating has long been seen as the only solution for decorative coatings on plastics, to ensure hardness and a bright colour. All environmentally friendly alternatives involve using a transparent top layer which influences on colour values.
Cromatipic® is a dry plating Cr-process that achieves Cr(VI)-free decorative functional Chromium coatings. It is an environmentally friendly process, which gives no corrosion risk, provides excellent adhesion on thermoplastics and an excellent resistance to humidity. It is a two layer process consisting of a spray UV coat layer and Physical Vapour Deposition (PVD) coating.
The regular ten basic process steps needed for POP plating on plastic will be reduced to only three in case of Cromatipic®.
The Cromatipic® process combines a non-solvent Zero VOC’S UV curing basecoat and high performance pure Chrome PVD sputtering system layer.
It is a highly controllable process and it does not require using any topcoats to deliver significant results for plastic moulders and metal decorators.
The innovative clean technology passes specific automobile specifications such as: CASS test, cycle corrosion, durability and weathering performance, thermal cycle test, chemical resistance and others.
Many kinds of plastics can be treated with this surface finish and a wide colour range is achievable.
