Abstract
A process for depositing a metal-adhesive, hydrophobic and electrically conductive coating based on electrically conductive microparticles and on a polymer matrix P comprising at least one thermoplastic fluoropolymer P1 and a thermosetting resin P2, comprises: in a first container, dissolve the polymer P1 in an organic solvent; in a second container, disperse the electrically conductive microparticles in an organic solvent; add, in the first container, the thermosetting resin P2 in the liquid state; mix the contents of the containers, then deposit the mixture on the substrate; crosslink the resin P2 and remove the solvents, to obtain a first coating; then impregnate the surface of the substrate with an additional resin solution P2 dissolved in a third solvent, which is a solvent of the resin P2 and a non-solvent of the polymer P1; eliminate the third solvent and crosslink while compressing the additional resin P2 in order to obtain the targeted final coating.
