Use of an organopolysiloxane/polyurea block copolymer according to formula (1), where R is a univalent hydrocarbon radical with 1 to 20 carbon atoms, optionally substituted by fluorine or chlorine, X is an alkylene radical with 1 to 20 carbon atoms in which methylene units that are not adjacent to one another can be replaced by -O- groups, or is an arylene radical with 6 to 22 carbon atoms, A is an oxygen atom or an -NR'- amino group, R' is water or an alkyl radical with 1 to 10 carbon atoms, Y is a bivalent hydrocarbon radical with 1 to 20 carbon atoms, optionally substituted by fluorine or chlorine, B and B' are a reactive or non-reactive end group that is bonded covalently to the polymer, n is a number from 1 to 4000 and a is a number starting from at least 10, as a coating on a pre-treated plastic surface, the polar surface energy fraction thereof being at least twice that of the untreated plastic surface. |
