Claims14
An adhesive comprising a radiation cured silicone gel, wherein the silicone gel comprises a crosslinked poly diorganosiloxane material, a noncrossedlinked polydiorganosiloxane fluid, and a silicate resin tackifier.
An adhesive comprising a radiation cured silicone gel, wherein the silicone gel comprises a crosslinked poly diorganosiloxane material and a poly(dimethylsiloxane-oxamide) linear copolymer.
An adhesive formed by exposing a composition comprising a poly diorganosiloxane material to at least one of electron beam irradiation and gamma irradiation at a sufficient dose to crosslink the poly diorganosiloxane material and form a radiation cured silicone gel, wherein the silicone gel comprises a crosslinked poly diorganosiloxane material and a noncrosslinked polydiorganosiloxane fluid.
An adhesive formed by exposing a composition comprising a poly diorganosiloxane material to at least one of electron beam irradiation and gamma irradiation at a sufficient dose to crosslink the poly diorganosiloxane material and form a radiation cured silicone gel, wherein the silicone gel comprises a crosslinked poly diorganosiloxane material and a poly(dimethylsiloxane-oxamide) linear copolymer.
