  • Method for gluing film-like substrates
    Patent number: 8455102
    Abstract: A method for adhesively bonding film-like substrates, in which a two-component polyurethane adhesive is applied to a film and then a second film is applied, a two-component polyurethane adhesive being used that consists of—a component A containing at least one prepolymer having at least two NCO groups,—a component B containing at least one polymeric or oligomeric crosslinker having at least two groups that react with NCO groups, wherein component B contains 0.05 to 5 wt. % of a low-molecular-weight compound C, which—should have a nucleophilic group that reacts with NCO groups and—contains a hydrogen-bridging group, selected from O?C—O? or O?C—C—O? or O?C—C?C—O? or protonated forms.
    Type: Grant
