1. A composition, comprising an aqueous dispersion of epoxy resin particles having at least two 1,2-epoxide groups, and one or more anti-adhesive agents, wherein:
the one or more anti-adhesive agents comprises an ethoxy-functional silicone emulsion, composed of octyl tri-ethoxy silane, included at 60% by volume, on the basis of the aqueous dispersion of epoxy resin particles, in order to generate an anti-adhesive coating, capable of being sprayed onto metal substrates, such that an adhesion of a section transfer medium to metal surfaces is prevented.
