Abstract
The invention relates to a composition including (i) at least one polyamide and at least one copolymer (A) of ethylene with at least one comonomer chosen from unsaturated carboxylic acids, esters of unsaturated carboxylic acids or vinyl esters of saturated carboxylic acids and (ii) being in powder form. These compositions are subsequently deposited on metal substrates and then a highly corrosion-resistant coating is obtained by melting.
