The basic chemical reactions, used to synthesize monomer and polymer resins and the chemistry involved in the use of curing agents to polymerize the resins, have been extensively studied and are well documented. This section serves as a summary only of those polymers that are primarily used in adhesives formulations for electronic applications. Among these polymers are the epoxies, silicones, polyurethanes, polyimides, acrylates, cyanate esters, and cyclo-olefins. Further technical detail for these polymers maybe acquired through literature searches in the transactions of the American Chemical Society (Polymer Group), Society of Plastics Engineers (SPE), and the Society for the Advancement of Materials and Process Engineers (SAMPE). 

In summary, there are erosion tests that are applicable to plastics, but there is not a large amount of research activity in this area. Most materials engineers are of the opinion that plastics are very resistant to erosion/corrosion processes. This is the case when the fluids are a low velocity or impinge with low energy, but when plastics are used for applications like jet airplane windows some of the tests described may be needed to make sure that they do not fail by erosion.
