Beschreibung
Zusammenfassung:	Medical articles include a substrate with a layer of a siloxane-based gel adhesive composition. The gel adhesive composition includes a crosslinked polymeric siloxane matrix, and an extractable polymeric fluid with a weight average molecular weight greater than 275,000 grams/mole. The extractable polymeric fluid is 26-80 weight % of the gel adhesive composition. The gel adhesive composition may also include a siloxane tackifying resin. 本发明提供一种医疗制品，该医疗制品包括具有硅氧烷基凝胶粘合剂组合物层的基底。该凝胶粘合剂组合物包含交联的聚合物型硅氧烷基质和具有大于275,000克/摩尔的重均分子量的可萃取的聚合物流体。该可萃取的聚合物流体为该凝胶粘合剂组合物的26重量％-80重量％。该凝胶粘合剂组合物还可包含硅氧烷增粘树脂。
