<p>The invention relates to an adhesive containing components A and B, whereby an amorphous polyester with a molecular weight (Mn) of at least 8,000 and a enthalpy of melting no higher than 20 mJ/mg is contained as component A, and an amorphous polyester with a molecular weight (Mn) of less than 8,000, especially 1,000 to 6,500, and having a glass transition temperature of no higher than 60 ~C, especially of -10 to 40 ~C, is contained as component B. The adhesive has a melting viscosity of 500 to 25,000 mPas (Brookfield RVT DVII, 90 ~C, Spindel 27) and a softening point of 70 to 100 ~C (ASTM E28). The inventive adhesive is especially well suited for bonding polyolefin substrates.</p> |
