Plasma-finish is the youngest department of PINK. It emerged in June 2007 through a majority stake acquired in Plasma-finish GmbH in Schwedt. As a result, the Wertheim-based
company committed itself to the future-oriented markets of surface technology.
Since 1995 Plasma-finish has been developing und producing systems of high quality for surface activation, cleaning und coatings in the sector of low-pressure
plasma technology.
What is Plasma?
When a piece of matter is continually supplied with energy, its temperature increases and passes from a liquid state to a gaseous state. If more energy is now supplied, the
kinetic energy of the elementary particles increases to a point at which the atomic shell disintegrates and produces radicals, negatively charged electrons, and positively
charged ions. This mixture is referred to plasma and is often called the "fourth state of matter."

This low-pressure plasma can be created artificially by exposing gases to high-frequency electromagnetic fields in a vacuum chamber and causing them to discharge. The gas
will become ionized and generate chemical radicals and ultraviolet radiation. In this manner a highly reactive process gas is created, which reacts with the surface of the
material to be treated.
