Abstract
An article including a release liner with an adhesive layer disposed thereon, the adhesive layer including a plurality of stripes of a first pressure-sensitive adhesive and of a second pressure-sensitive adhesive, arranged in a generally alternating pattern. The first pressure-sensitive adhesive is a silicone-based pressure-sensitive adhesive that includes a silicone block copolymer elastomer comprising hard segments that each comprise at least one polar moiety, and the second pressure-sensitive adhesive is an organic polymeric pressure-sensitive adhesive.
Claims19
An article comprising:
- a first release liner comprising a fluorosilicone release surface on at least a first major surface thereof;
- a primary adhesive layer disposed on the first major surface of the release liner, wherein the primary adhesive layer comprises a plurality of stripes of a first pressure-sensitive adhesive and of a second pressure-sensitive adhesive, arranged in a generally alternating pattern along a longitudinal extent of the release liner;
- wherein the first pressure-sensitive adhesive is a silicone-based pressure-sensitive adhesive that comprises a silicone block copolymer elastomer comprising hard segments that each comprise at least one polar moiety,
- wherein the second pressure-sensitive adhesive is an organic polymeric pressure-sensitive adhesive,
- wherein the first pressure-sensitive adhesive provides a volume fraction of the primary adhesive layer that is from greater than 11%, to about 80%;
- and wherein the primary adhesive layer exhibits an Elevated Humidity/Static Shear Test result of >30000 minutes.
