Abstract
The adhesion of poly(arylene sulfide) coatings to metal substrates is improved by incorporating an effective amount of finely divided manganese dioxide into a poly(arylene sulfide) primer coat to prime the metal substrate. The primer coat can subsequently be coated with a poly(arylene sulfide) coating or with any other suitable finish coating which will adhere to the primer coat.
