Abstract (en)

Proposed is an anticorrosive multilayer coating system for metal surfaces, more particularly pipes and storage tanks, comprising at least a primer coat (a) based on a non-conductive binder, followed by a second or further top coats (b), characterised in that the primer coat (a) is an electroinsulating powder coating layer based on an epoxy resin, alkyd resin, polyester resin, melamine-containing resin, polyurethane resin and/or polyacrylate resin, and, optionally, a filler, pigment and/or adjuvant, and the outer top coat (b) is an electrically conductive powder coating layer based on an epoxy resin, alkyd resin, polyester resin, melamine-containing resin, polyurethane resin and/or polyacrylate resin incorporating 0,1 to 50% by weight of an electrically conductive resin, filler, pigment and/or adjuvant capable of providing a conductive outer layer with, optionally, a structured and/or wrinkle finish, calculated on the overall weight of this outer layer.
