Abstract:
Disclosed herein are temperature switchable adhesive assemblies, which maintain tack above and below the switching temperature. The temperature switchable adhesive assemblies comprise a backing, a first adhesive layer comprising a temperature switchable pressure sensitive adhesive disposed on the backing, and a second adhesive layer comprising a non-switchable pressure sensitive adhesive disposed on the first adhesive layer. The temperature switchable adhesive assemblies have use in medical, consumer, and industrial applications.
