Abstract
An adhesive useful in forming composites includes components A and B. Component A includes at least one polyester with a molecular weight (M ) of at least 8000 and has a total enthalpy of fusion of at most 20 mJ/mg. Component B includes at least one polyester with a molecular weight (Mn) of less than 8000 and a glass transition temperature of at most 60° C. The adhesive preferably has a melt viscosity of 500 to 25,000 mPas (Brookfield RVT DVII, 140° C., spindle 27) and a softening point of 70 to 100° C. (ASTM E28).
