摘要:
The invention relates to formulations of aqueous dispersion adhesives based on aqueous polyurethane or polyurethane-urea dispersions, and to the use of the adhesive formulations for the adhesive bonding of foam substrates by the spray coagulation process. The dispersion comprises as disperse phase at least one polymer which after drying is semicrystalline or crystalline and has a melting temperature in the range from 30 to 80° C. and an enthalpy of fusion of ≥35 J/g. The formulation comprises at least one plasticizer and optionally at least one tackifier resin.
