Abstract
An adhesive article includes a first substrate, a first adhesive layer positioned adjacent the first substrate, a second substrate, and a first meltable layer positioned adjacent to the first adhesive layer and the second substrate. The meltable layer has a ring and ball (R&B) softening point of between about 60° C. and about 180° C.
Claims18
An adhesive article comprising:
- a first substrate;
- a first adhesive layer positioned adjacent the first substrate;
- a second substrate;
- and
- a first meltable layer positioned adjacent to the first adhesive layer and the second substrate, wherein the meltable layer has a ring and ball (R&B) softening point of between about 60° C. and about 180° C.

A method of debonding a first substrate form a second substrate, wherein the first substrate and the second substrate are assembled together with an adhesive tape construction, the method comprising:
- providing an adhesive tape construction having an adhesive layer and a meltable layer, wherein the adhesive layer and the meltable layer are attached;
- heating the adhesive tape construction to a temperature to or above a R&B softening point of the meltable layer;
- and
- applying force between the first and second substrates and the adhesive layer and the meltable layer to trigger cohesive failure of the heat sensitive layer,
- wherein the R&B softening point of the meltable layer is between about 60° C. and about 180° C.
