Although most metals exhibit high surface energies, the absorption of water vapour and especially organic particulate matter from the environment results in an invisible layer of contamination of low surface energy. This layer is effectively and efficiently removed by plasma cleaning, resulting in greatly increased wettability and much improved adhesion characteristics.
