Coating large areas places enormous demands on the mechanical, physical and chemical homogeneity of the coating material. Metal strips and solar cells, to name an example, receive an even, high-quality coating. Leading suppliers of large area coating equipment and their customers rely on COTEC’s PVD vapor deposition materials. Our products meet the high quality, reliability and long-term durability demands which are key to our customers’ success.

The ultrathin layers on the substrates originate, for instance, from physical vapor deposition (PVD). The substrate material can be anything from glass, plastics, paper or a metal strip. Depending on the requirement, the layers are metallic, dielectric or any combination thereof. The materials required for the processes are developed by COTEC and manufactured according to special formulas.

For example, active photocatalytic titanium dioxide layers are created during the continuous large area coating process for metal strips. In solar thermal energy where solar energy is used directly for heating, cooling and heating water, copper or aluminum strips in so-called “air to air facilities”, may be continuously provided with absorbent films. On the one hand, these layers produce low thermal emissions and the highest possible absorption. At the same time, resistance against exterior influences is improved.
