An adhesion issue occurs when two different materials will not adhere to one another. Many different factors can cause an adhesion issue. One of the most important factors when dealing with an adhesion issue is the surface energy of the materials. If the surface energy of both materials is high, then there will be better adhesion. However, if it is low, there can be an adhesion issue. One way to improve the surface energy of a material is to treat it with plasma. The best way to achieve this is to treat at least one of the materials with a low pressure plasma system.
