Abstract: Siloxane-based gel compositions are prepared from room temperature condensation curable mixtures that include 0.5-45% by weight silicone resin with at least two hydroxyl groups, 99.5-55% by weight of at least one silanol-terminated siloxane fluid, and a co-curable compound with an amino group. The siloxane-based gel compositions can be used as adhesives or sealants in medical articles.

Abstract: Siloxane-based gel adhesives with improved shear holding power are prepared from curable compositions. The curable compositions include a siloxane fluid with a viscosity of at least 1,000,000 centiPoise, a siloxane-(meth)acrylate co-polymer, and siloxane tackifying resin. The curable compositions can contain an initiator or can be cured by e-beam radiation without an initiator. The siloxane-(meth)acrylate copolymer is the reaction product of a reaction mixture of an ethylenically unsaturated siloxane-containing macromer, an alkyl (meth)acrylate monomer; optionally a reinforcing monomer, and an initiator.
