Evaluated Alternative SUPERCHROME PVD COATING – a green alternative to hexavalent chrome plating SUPERCHROME PVD COATING provides a chrome finish with a decorative character for plastic substrates. Hexavalent chromium is not used in this process. SUPERCHROME PVD COATING is a two-layer coating consisting of a UV cured base coat and a chromium PVD layer on top. Unlike conventional PVD coatings, SUPERCHROME PVD COATING requires no protective top-coat to interfere with the chrome finish. VTI provides the SUPERCHROME PVD COATING process and system technology.
