Abstract
Official abstract text for this publication.
A membrane composite comprising a polymeric membrane panel, an adhesive layer, and a release liner, where the adhesive layer is a pressure-sensitive adhesive that is at least partially cured, and includes at least two distinct regions with the at least two regions having distinct states of cure.
First claim
Opening claim text (preview).
1 . A membrane composite comprising: a. a polymeric membrane panel; b. an adhesive layer; and c. a release liner, where the adhesive layer is a pressure-sensitive adhesive that is at least partially cured, and includes at least two distinct regions with the at least two regions having distinct states of cure. 2 . The membrane composite of claim 1 , where the adhesive layer is in contact with substantially all of one planar surface of the membrane panel. 3 . The membrane composite of claim 1 , where the adhesive layer includes a UV-cured acrylic resin. 4 . The membrane composite of claim 1 , where the adhesive layer includes a lap region. 5 . The membrane composite of claim 4 , where the adhesive layer includes a central region. 6 . The membrane composite of claim 5 , where the adhesive layer includes a second lap region. 7 . The membrane composite of claim 6 , where the first lap region and optional second lap region have a higher state of cure than the central region. 8 . The membrane composite of claim 7 , where the cure state within the lap region is at least 1% higher than in the central region. 9 . The membrane composite of claim 8 , where the cure state within the lap region is at least 5% higher than in the central region. 10 . The membrane composite of claim 9 , where the cure state within the lap region is at least 10% higher than in the central region. 11 . The membrane composite of claim 7 , where the cure state within the lap region is at least 85% of full cure for the adhesive. 12 . The membrane composite of claim 11 , where the cure state within the lap region is at least 90% of full cure for the adhesive. 13 . The membrane composite of claim 7 , where the cure state within the central region is at most 84% of full cure for the adhesive. 14 . The membrane composite of claim 13 , where the cure state within the central region is at most 80% of full cure for the adhesive.
