Abstract: An aqueous adhesive formulation; containing a mixture of: at least one partially crystallised or crystalline polyurethane having a fusion temperature of 35 to 80° C. and an enthalpy of fusion of ?35 J/g as component A; at least one plasticiser as component B; at least one salt as component C; and optionally at least one further polymer as component D. The mixture contains: 30 to 94.9 wt. % component A; 5 to 45 wt. % component B; 0.001 to 3 wt. % component C; and optionally 0 to 30 wt. % component D, each based on the total of the amounts of the components A, B, C and optionally D present in the mixture.

Abstract: The invention relates to the use of an aqueous dispersion containing at least one polyurethane-polyurea polymer formed from (a) at least one difunctional polyester polyol having a number-average molecular weight of 400 to 5000 g/mol, (b) at least one difunctional polyol component having a number-average molecular weight of 762 to 399 g/mol, c) at least one diisocyanate and (d) at least one chain extender optionally having at least one ionic group, for the bonding of at least two substrates by application of the aqueous dispersion to at least one of the substrates to be bonded, subsequent drying of the dispersion present on the at least one substrate in order to obtain at least one adhesive layer, and contacting of the at least one adhesive layer with a further substrate or with an adhesive layer present on a further substrate at a pressure of from 0.1 to 5 bar(a) and a temperature of less than 40° C.

Abstract: 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.
