Abstract
A medical silicone pressure-sensitive adhesive composition is described that includes: organopolysiloxane A, organopolysiloxane resin B, organopolysiloxane crosslinker XL, organopolysiloxane extender CE, hydrosilylation catalyst D, solvent E and hydrosilylation inhibitor F, wherein the organopolysiloxanes A, CE and XL are chosen such that the molar ratio RHAlk=tH/tAlk is 3.5 to 8; and nH/nHis within 0.13 to 11, with:—tH=number of moles of hydrogen atom directly bonded to a silicon atom of the organopolysiloxanes XL and CE;—tAlk=number of moles of alkenyl directly bonded to a silicon atom of the organopolysiloxane A;—nH=number of moles of hydrogen atom directly bonded to a silicon atom of the organopolysiloxane XL;—nH=number of moles of hydrogen atom directly bonded to a silicon atom of the organopolysiloxane CE. Also described, is a method for coating a substrate by using the medical silicone pressure-sensitive adhesive composition, a coated substrate obtainable according to the method, and also a skin-adhesive article made by using the medical silicone pressure-sensitive adhesive composition.
