Zusammenfassung:An adhesive composition of a pre-crosslinked halogenated butyl rubber component at a concentration of about 30 to 95 PPHR; a styrene-ethylene/butylene-styrene block thermoplastic rubber at a concentration of about 5 to 50 PPHR; a halogenated substantially non-crosslinked butyl rubber at a concentration of about 0 to 20 PPHR; a pre-crosslinked substantially non-halogenated butyl rubber at a concentration of about 0 to 20 PPHR; an EPDM rubber at a concentration of about 0 to 5 PPHR; a polyisobutylene rubber at a concentration of about 0 to 20 PPHR; a styrene-butadiene rubber at a concentration of 0 to 20 PPHR; an aliphatic hydrocarbon resin mixture at a concentration of about 25 to 90 PPHR; and an aromatic hydrocarbon resin mixture at a concentration of about 1 to 31 PPHR; and at least one solvent in an amount sufficient for dispersing the preceding components.
