The invention relates to a ready-to-use hot melt adhesive containing at least 95% of one or more polyolefin copolymer waxes, which have been prepared by means of metallocene catalysts, characterised in that the polyolefin copolymer wax consists of propylene and one or more further monomers selected from ethylene and branched or unbranched 1-alkenes having 4 to 20 C-atoms and the content of structural units derived from propylene in the copolymer waxes amounts to 80 to 99.9% by weight, and the hot melt adhesive has a surface tension of the melt, measured at a temperature of 170&#xb0; C., of at most 23 mN/m.
