Abstract
A building material comprising a substrate layer and a pressure-sensitive adhesive layer, where the pressure-sensitive adhesive layer includes expandable graphite.
Claims11
A composite comprising:
- i. a polymeric sheet;
- ii. a layer of pressure-sensitive adhesive, where the layer of pressure-sensitive adhesive includes first and second planar surfaces, and where the first planar surface of the pressure-sensitive adhesive layer is fixedly attached to the polymeric sheet;
- iii. concentrated region of expandable graphite, where the concentrated region of expandable graphite is at or proximate to the second planar surface of the pressure-sensitive adhesive, and where the concentrated region of expandable graphite is discontinuous to thereby allow the pressure-sensitive adhesive to be exposed;
- and
- iv. a release liner or film removably attached to the second planar surface of the pressure-sensitive adhesive.

A composite prepared by a process comprising:
- i. providing a layer of pressure-sensitive adhesive;
- and
- ii. dropping expandable graphite on to the layer of pressure-sensitive adhesive to thereby form a composite comprising
- a polymeric sheet;
- b. the layer of pressure-sensitive adhesive, where the layer of pressure sensitive adhesive includes first and second planar surfaces, and where the first planar surface of the pressure-sensitive adhesive layer is fixedly attached to the polymeric sheet;
- c. the dropped expandable graphite in a concentrated region, where the concentrated region of expandable graphite is at or proximate to the second planar surface of the pressure-sensitive adhesive, and where the concentrated region of expandable graphite is discontinuous to thereby allow the pressure-sensitive adhesive to be exposed;
- and
- d. a release linear or film removably attached to the second planar surface of the pressure-sensitive adhesive.
