Abstract

Le procédé ci-décrit est caractérisé en ce que la laque d'électro-trempage est filtrée, en plus des opérations usuelles de purification, sans air comprimé sur un milieu d'adsorption qui adsorbe des substances hydrophobes dont la tension superficielle est <= 35mN/m, de préférence des homo- ou copolymères d'éthylène, propylène, butène-1 ou butène-2, qui éventuellement contiennent encore d'autres comonomères homopolaires.
