    Abstract: A method for producing biodisintegratable composite foils with an aqueous polyurethane dispersion adhesive. The method involves adhesive-bonding a first substrate to a second substrate with use of the aqueous polyurethane dispersion adhesive. At least one of the first substrate and the second substrate is made of a biodisintegratable polymer foil, and at least 60% by weight of the polyurethane contains diisocyanates, polyesterdiols, and bifunctional carboxylic acids. The bifunctional carboxylic acids are dihydroxycarboxylic acids or diaminocarboxylic acids.

  • Patent number: 8951642
    Abstract: An aqueous two-component aqueous dispersion adhesives, including in particular polyether-polyurethane polymers and ethylene vinyl acetate copolymers (EVA) having a glass transition temperature of greater than 0° C. The dispersion adhesives are optimally suited for use as contact adhesives, and for gluing plastic membranes. It has been demonstrated that the adhesives or the adhesive composite items produced therewith are characterized by an exceptionally low plasticizer absorption behavior, and contact adhesion. The good heat resistance and good bonding to various bases are also advantageous.

  • Patent number: 8932721
    Abstract: The present invention relates to laminates of a plasticizer-containing plastic, obtained by bonding by means of a moisture-reactive hot-melt adhesive which comprises at least one aldimine and at least one polyurethane polymer which contains isocyanate groups and is solid at room temperature. The bonded assembly is notable for improved adhesive, particularly following heat/moisture storage or alternating storage. Preferred embodiments of such laminates are bonded films or film-laminated supports, the film preferably being a pPVC film.
