Abstract (en)
[origin: WO8703016A2] The process described above is characterized by the fact that the electrophoretic paint, in addition to undergoing the usual purification operations, is filtered without compressed air on an adsorption medium which adsorbs hydrophobic substances having a surface tension <= 35mN/m, preferably homo- or co-polymers of ethylene, propylene, butene-1 or butene-2 which may also contain other homopolar co-monomers.

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.
