  • Method for adhesively bonding substrates using adhesives
    Patent number: 10745591
    Abstract: The present invention relates to a method for adhesively bonding substrates, said method comprising the following steps: I) at least one adhesive component (a) and at least one isocyanate component (b) are applied between at least two substrates; II) the substrates are pressed together. The method is characterized in that in step I), the adhesive component and the isocyanate component are applied separately to the substrate. The invention further relates to a composite obtained according to said method. In a preferred embodiment, an aqueous polyurethane dispersion or a polyurethane solution in organic solvents is used as the adhesive component.
