Abstract (en)
In coating metal units or structures with a heat-hardening powder based on a polyester resin and/or an epoxy resin, which is sprayed on by means of an electrostatic spray gun and then polymerised in an oven, the pieces to be coated are pre-treated by: (a) an electrolytic zinc plating; and (b) application of a coat of varnish, followed by drying, baking or polymerisation of the varnish. This coating acts as a bonding underlayer between the metal and the polyester and/or epoxy resin outer coating. Pref. the varnish is acrylic and is polymerised in an oven. The thickness of the varnish layer is 2-30 (5-15) microns. The varnish is applied by dipping or spraying.
Abstract (fr)
Avant l'application d'un revêtement externe à base de résine polyester ou époxy, ou d'un mélange des deux par projection à l'aide d'un pistolet électrostatique, on effectue successivement les deux opérations suivantes sur les pièces à recouvrir : a.- traitement initial de zingage par procédé électrolytique, b.- application d'une couche d'un vernis acrylique, puis polymérisation de ce revêtement dans un four, le revêtement intermédiaire ainsi prévu étant apte à servir de sous-couche de liaison entre le métal et le revêtement externe.
