摘要:
The invention relates to a method for applying a protective coating to a substrate, such as metallic pipe, which comprises applying onto the substrate a liquid curable polymeric composition capable of curing to a substantial extent within about 24 hours at less than about 80.degree. C., then applying one or more polymeric layers, the innermost of which is capable of interacting with said curable composition, and permitting the composition to cure. In certain embodiments the polymeric layer is applied as a polymeric article, in other embodiments a multiple layer polymeric covering is applied over the curable composition.
