Patent ID: 7914645

Claim:
A method of adhering a device to a wet biological surface, which comprises applying to the device a silicone adhesive composition, wherein the silicone adhesive composition comprises: (i) 13 to 25 weight percent of a silicone resin that a cohydrolysis product of a trialkyl hydrolyzable silane and an alkyl silicate in which the cohydrolysis product contains a plurality of silicon-bonded hydroxy groups; (ii) 8 to 20 weight percent of a linear organopolysiloxane fluid containing terminal silicon-bonded hydroxy groups having a viscosity above 200,000 mm 2 /s at 25° C.; (iii) 5 to 30 weight percent of a trialkylsiloxy terminated polyorganosiloxane fluid having a viscosity of 100,000-600,000 mm 2 /s at 25° C.; (iv) 5 to 25 weight percent of a water soluble muco-adhesive polymer selected from the group consisting of a poly(ethylene oxide) polymer having a molecular weight of 100,000 to 8,000,000, an acrylic acid polymer having a molecular weight of 500,000 to 4,500,000,000, and a hydroxyethylcellulose polymer having a molecular weight of 90,000 to 1,300,000,000; and optionally, (v) up to 35 weight percent of a solvent selected from the group consisting of aliphatic hydrocarbons, aromatic hydrocarbons, esters, volatile linear and cyclic silicone compounds; and placing the device with the applied silicone adhesive composition to the wet biological surface, wherein the device is a denture, a hairpiece, a prosthesis, an ostomy, a wound dressing, a tape, a buccal patch, or a transdermal patch, and the wet surface is skin, the buccal cavity, the gums, the mucosal linings of intranasal passages, the alimentary canal, vaginal and rectal walls, and wet components of botanical origin.
