Copper Finishing

Copper components can be finished in a
vast variety of ways. The finish used for
any given Copper component is dependent
upon function and/or aesthetics. Copper
naturally forms a protective oxide layer on
exposure to the elements. This layer is
normally blue – green and may or may not
be desirable.
The blue – green patina develops over time
but its development can be enhanced and
accelerated by the use of commercially
available oxidising agents.
If the tarnished patina of Copper is not
desirable, the material can be protected
using a lacquer coating. An acrylic coating
with benzotriazole as an additive will last
several years under most outdoor,
abrasion-free conditions.
