ABSTRACT:
Hydrocolloid adhesive compositions for use as wound dressings or ostomy/prosthesis adhesives are disclosed. These adhesive compositions are made of a mixture of a hydrophobic, unsaturated, elastomeric homopolymer, a polyisobutylene tackifier and a hydrocolloid absorbent which is cross-linked by 5-200 kGy gamma radiation to provide a cross-linked matrix having a wet integrity value of at least about eighty percent, a shear hold value of at least about 500 min/500 g and a dry cohesive strength which prevents adhesive composition breakage or delamination. Methods of using such wound dressings or ostomy/prosthesis adhesives and methods of making the hydrocolloid adhesive compositions are also disclosed.
