More Information
Summary: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. 由可固化组合物制备具有改善的剪切保持力的硅氧烷基凝胶粘合剂。该可固化组合物包含具有至少1,000,000厘泊的粘度的硅氧烷流体、硅氧烷-(甲基)丙烯酸酯共聚物和硅氧烷增粘树脂。该可固化组合物可含有引发剂或者可在无引发剂的情况下通过电子束辐射来固化。该硅氧烷-(甲基)丙烯酸酯共聚物为烯键式不饱和的含硅氧烷大分子单体、(甲基)丙烯酸烷基酯单体的反应混合物的反应产物；任选的加强单体和引发剂。
