| 摘要 |
The invention relates to a composition for treating metal surfaces and for separating metals or metal alloys from plastic surfaces, containing a) at least one polymer as component A made of structural element (1) and at least three structural elements from a group comprising (2), (3), (4), (5); b) wat er or another solvent suitable to solve, disperse, suspend, or emulsify the polymer as component B; c) optional surface-active compounds, dispersing agents, suspending agents, and/or emulsifiers as component C. The invention also relates to a method for treating a metal surface and a method for separating metals or metal alloys from a plastic surface, the metal surface or plastic surface being brought into contact with a polymer (component A). Als o disclosed is the use of polymers (component A) to treat metal surfaces and separate metals or metal alloys from a plastic surface and polymers made of special components A'a, A'b, and A'c. |
