  • Patent number: 11814558
    Abstract: Described is a process for producing adhesive-coated articles, wherein an aqueous dispersion adhesive composition comprising a dispersed adhesive polymer and a dissolved polyvinylpyrrolidone is applied at high web speed to a film substrate using a coating machine having at least one rotating roller and wherein the coated film substrate may optionally be bonded to a further substrate. Also described is the use of polyvinylpyrrolidone as a defoamer for aqueous dispersion adhesive compositions applied to a film substrate using a coating machine having a rapidly rotating roller.
    Type: Grant

  • Publication number: 20230092087
    Abstract: The use of an aqueous polyurethane dispersion adhesive is described for producing composite foils which are biodisintegratable at home compost conditions where at least two substrates are adhesive-bonded to one another with use of the polyurethane dispersion adhesive, where at least one of the substrates is a polymer foil which is biodisintegratable at home compost conditions. At least 60% by weight of the polyurethane is composed of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from dihydroxy carboxylic acids and diamino carboxylic acids, wherein the polyurethane has no melting point above 20° C. or wherein the polyurethane has a melting point above 20° C. with an enthalpy of fusion lower than 10 J/g, and wherein a film of the polyurethane adhesive is biodegradable at home compost conditions.
