Abstract
The method includes the steps of: preparing an organic mixture of oil, monomers selected among acrylic acid—and methacrylic acid esters and at most 25% of an acrylic or methacrylic monomer having an acide, amide, amine or epoxy group; placing the mixture in mini-emulsion in an aqueous phase in the presence of a co-solvent, preferably of the polyalkylene glycol type; and copolymerising the monomers in emulsion. When the emulsion is applied in a thin coating on a metal surface, it provides simultaneously a dry appearance, efficient protection and a pre-lubricating effect.
