The pressure sensitive adhesive composition further comprises (wt.%): a plasticizer (1-5); at least one filler and rheology modifier (1-5); an antioxidant (0.1-0.5); ultra-violet radiation absorber; a stabilizer (0.1-0.5); and a desiccant (2-8). The uncured rubbery polymer blend is selected from ethylene propylene norbornadiene terpolymer or ethylene propylene dicyclopentadiepe terpolymer (1-5 wt.%), ethylene propylene hexadiene terpolymer (2-10 wt.%), chlorobutyl rubber (5-25 wt.%), first polyisobutylene (2-10 wt.%), halogenated butyl rubber, and halogenated copolymer of p-methylstyrene and isobutylene. The pressure sensitive adhesive composition further comprises a second polyisobutylene having an average viscosity molecular weight less than 100000 and present in an amount of 0.1-3 wt.%. The first polyisobutylene has average viscosity molecular weight of greater than 100000. Preferred Components: The cure accelerator comprises tetramethylthiuram disulfide and benzothiazyl disulfide, the sulfur activator having zinc oxide, and the curing vulcanizing agent having sulfur. The plasticizer comprises paraffinic process oil. The filler and rheology modifier is selected from at least one calcium carbonate, talc, and fumed silica. The desiccant comprises calcium oxide. The antioxidant comprises tetrakismethylene(3,5-di-t-butyl-4-hydroxyhydro-cinnamate) methane. The ultra-violet radiation absorber comprises carbon black (2-5 wt.%). The stabilizer comprises tetrachchloro-p-benzoquinone. The adhesive layer has a peel strength of 20-30 pounds per square inch after 24 hours of being applied to the substrate at room temperature.
