摘要:
The invention relates to a polyurethane adhesive, in particular for laminating foils, wherein the PU adhesive contains between 0.1 to 20 wt% of a low-molecular epoxy comprising at least one epoxy group and at least one hydroxy group. The epoxy is chemically unbonded or is chemically bonded by means of at least one hydroxy group. The invention further relates to the use of the adhesive for adhesively bonding foils, to a method for producing multilayer foils, and to multilayer foils adhesively bonded using the adhesive described above.
