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.
