Abstract
A membrane composite comprising a polymeric membrane panel, an adhesive layer, and a release member, where the adhesive layer is a pressure-sensitive adhesive that is at least partially cured, and where the adhesive layer has a thickness of at least 102 μm.
Claims20
A roofing membrane composite comprising:
- a. a polymeric membrane panel for providing a weatherproof polymeric barrier to a building structure;
- b. an adhesive layer;
- and
- c. a release member, where the adhesive layer is an ultraviolet (UV) cured pressure-sensitive adhesive that is at least partially cured and where the at least partially cured pressure-sensitive adhesive is characterized by a cross-linked infinite polymer network, and where the adhesive layer has a thickness of at least 102 μm.
