Method for gluing film-like substrates

The invention relates to a method for gluing film-like substrates, in which a two-component polyurethane adhesive is applied onto a film and thereafter a second film, wherein a two-component polyurethane adhesive is used consisting of a component A containing at least one prepolymer having at least...

Beschreibung
Zusammenfassung:	The invention relates to a method for gluing film-like substrates, in which a two-component polyurethane adhesive is applied onto a film and thereafter a second film, wherein a two-component polyurethane adhesive is used consisting 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 cross-linking agent that comprises at least two groups reactive with NCO groups. The invention is characterized in that component B contains 0.05 to 5% by weight of a low-molecular compound C, wherein said compound C shall comprise a nucleophilic group which is reactive to NCO groups, and a group forming H bridges, selected from O = C - O - or O = C -C- O - or O = C - C = C - O - or protonated forms.
