The reactive hot-melt adhesive is still plastically formable, though viscous, after cooling and contains a mixture of - at least one thermoplastic material, - at least one isocyanate-based binder, and - at least one thixotropic agent, and the isocyanate content, based on the total hot-melt adhesive, is in the range from 0.01 to 10 % by weight.
