Chemical Reactions and Functionalisation
Vacuum plasma operates at low pressures to turn the remaining gaseous molecules in to an energetic soup of electrons, ions and radicals with immense energy.
This energy is normally used for treatment, which in most cases is an addition of a small amount of functional groups on the material surface to influence the chemistry between the coating/ paint/ ink or adhesive which is being applied to the treated material.
Where a specific surface chemistry is required, input gases and liquids can be added to create a vessel with various chemical reactions taking place. This can be used to add functional groups such as amino and hydroxyl, or adding fluorine to create a non stick surface.
Not often a requirement for normal adhesion and cleaning issues, this advanced processing technique is used for more resilient materials and for treatment of powders and smaller components in rotating vacuum systems.
