A pressure-sensitive adhesive having a constant adhesiveness in a temperature range from -40 DEG C to 110 DEG C and a uniform reversibility may be produced from: 40 to 90 % by weight of a first aqueous dispersable adhesive made of one or several substances of the group formed by vinyl ester, natural rubber, vinyl acetate, styrol-butadiene, polyvinyl isobutylene, vinyl alcohols, acrylic acid ester copolymers, polymethacryaltes, polyacrylic acid butyl ester, acryl-styrol copolymers, acryl-vinyl copolymers; 5 to 50 % by weight of at least one second organically soluble adhesive different from the first one from the group formed by rubber, polyvinyl chloride, dibutyl phthalate, trimethyl ester, IC resins, hydrated, aromatic hydrocarbon resins, balsamic resins, colophonium resins; and 0 to 20 % by weight of other additives, in particular thickeners. This pressure-sensitive adhesive allows initial reversible bonding of untreated plastic parts and possibly lacquered metallic parts in the automobile industry. |
