Abstract (en)

[origin: EP0059136A2] 1. Process for coating a metal substrate, particularly to produce an anticorrosion covering, according to which a primary layer and at least one layer of plastic are applied to the said substrate, the primary layer comprising a resin chosen from epoxyphenolic resins, mixtures of epoxy resins and phenolic resins and combinations of the said resins and mixtures of resins, while the last layer of plastic material is a layer of polyamide, after which the whole is heated until the outer layer of polyamide melts, the said process being characterised in that the said polyamide is applied continuously in the form of a suspension, in an organic liquid phase, of polyamide powder the particle size of which is below 40 microns, the thickness of the outer layer of polyamide being between 20 and 50 microns, the process being carried out continuously and in a single step.
