Adhesive compositions useful for use with medical devices, such as adhesive tapes, consist essentially of a homogeneous mixture of one or more polyisobutylenes or blends of one or more polyisobutylenes; a tackifying resin; a styrene copolymer; mineral oil; a water insoluble, water swellable, synthetic hydrocolloid which forms a gel when wet; and, an ethylene vinyl acetate copolymer which increases the dimensional stability of the final composition.

A moisture resistant adhesive composition for use in the presence of moisture, said adhesive consisting essentially of a substantially homogeneous mixture one a percent weight basis of from about 5% to abut 10% of one or more low molecular weight polyisobutylenes, from about 7% to about 15% of a styrene block copolymer, from about 12% to about 20% of mineral oil, from about 15% to about 30% of a water insoluble, water swellable synthetic hydrocolloid which is a polyacrylic acid metallic sal that forms a gel when it is wet, from about 1% to about 8% of an ethylene vinyl acetate copolymer which increases dimensional stability and from about 30% to about 40% of a tackifying resin.
