Abstract
A process is described for treating metal surfaces printed wiring boards and similar substrates to provide improved creep corrosion resistance on such surfaces. A modified organic solderability preservative composition is used in combination with an emulsion polymer to provide a modified polymer coating on the metal surface finish via a chemical reaction to provide enhanced corrosion protection of the surface.
