The present invention relates to the use of surfactants of the general formula (I) <?in-line-formulae description="In-line Formulae" end="lead"?>R-O-(A)<SUB>n</SUB>-(B)<SUB>m</SUB>-H (I)<?in-line-formulae description="In-line Formulae" end="tail"?> where R is a C<SUB>8</SUB>-alkyl radical, A is propylenoxy, B is ethylenoxy, n is an average value of from 0.8 to 2.0 and m is an average value of from 2.0 to 5.0 as a wetting agent for hydrophobic polymer surfaces, and to a wetting agent comprising a) from 0.5 to 50% by weight of at least one surfactant of the general formula (I) according to claim 1, b) from 1.0 to 10% by weight of a C<SUB>8</SUB>-alcohol and c) from 0.5 to 30% by weight of a compound of the general formula (IV) <?in-line-formulae description="In-line Formulae" end="lead"?>R-O-(A)<SUB>n</SUB>-H (IV)<?in-line-formulae description="In-line Formulae" end="tail"?> where R is a C<SUB>8</SUB>-alkyl radical, A is propylenoxy and n is an average value of from 0.8 to 2.0.
