Adhesion, corrosion - durability of joints

The durability of joints consisting of polymer and metal is often ruled by their resistance to corrosion. A comparison between paint layers and adhsive joints with respect to the adhesion mechanisms, polymer chemistry and corrosion mechanisms can give more detailed informations. An adhesive joint is compared to a paint a more closed system. In it the unevitable residuing monomers are entrapped, while in a paint they can evapourate through the surface.
