Beschreibung
Zusammenfassung:	Painting plastics substrates, which cleans the surface with an organic solvent and a mechanical surface treatment before coating with an adhesive layer of water-based adhesive to bond the applied paint. To paint plastics substrates, an adhesive layer is applied using a water-based adhesive with a further coating if required. Before the adhesive layer is applied, the surface of the plastics substrate is cleaned with an organic solvent or a mixture with an organic solvent content, together with one or more aliphatic and/or cycloaliphatic hydrocarbons with a boiling point of 25-315 degrees C and/or one or more aromatic hydrocarbons with a boiling point of 120-190 degrees C. The mixture of hydrocarbons and solvent contains 1-20 wt% of one or more other solvents. The adhesive coating contains one or more chlorinated and/or chlorine-free polyolefins. The surface of the plastics substrate is treated mechanically at the same time as it is cleaned.
