  • Publication number: 20220306916
    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.

  • Publication number: 20210395945
    Abstract: The invention relates to a method for producing a composite component, comprising the steps: i) applying an aqueous composition, which contains a polychloroprene dispersion and/or a polyurethane dispersion, to at least one nonwoven; ii) coagulating the aqueous composition on the nonwoven by bringing the aqueous composition into contact with a coagulant and/or heating to 80 to 220° C., in order to form a semifinished product; and iii) optionally attaching a decoration, which comprises an adhesive film; and iv) thereafter, shaping the semifinished product from step ii) or iii) by pressing and/or heating to 30 to 220° C., in order to obtain the composite component, characterized in that the aqueous composition contains at least one thickener.
