UV-curable polyester/epoxy adhesive

摘要

The present invention relates to a pressure sensitive adhesive tape comprising at least one pressure sensitive adhesive layer that is capable of being cured upon exposure to actinic radiation or electron beam radiation and comprises: (i) an epoxy containing material; (ii) an amorphous and branched polyester having a glass transition temperature of not more than 10 DEG C; (iii) and an effective amount of a photoinitiator when needed to initiate the curing. According to a method provided by this invention, the pressure sensitive adhesive tape can be used to join two substrates and create assemblies with excellent mechanical properties.
