The invention discloses a multifunctional organic hydrogen siloxane. The multifunctional organic hydrogen siloxane is prepared by using a fluorinated triaryl borane Lewis acid as a catalyst. The multifunctional organohydrogensiloxanes can be formulated as release coating compositions. Alternatively, the multifunctional organohydrogensiloxanes may be further functionalized with a curable group to form clustered functionalized organosiloxanes. The clustered functionalized organosiloxanes can be formulated as thermal radical curable adhesive compositions. 本发明公开了一种多官能有机氢硅氧烷，该多官能有机氢硅氧烷使用氟化三芳基硼烷路易斯酸作为催化剂来制备。该多官能有机氢硅氧烷可配制成防粘涂料组合物。另选地，该多官能有机氢硅氧烷可用可固化基团进一步官能化以形成簇合官能化有机硅氧烷。该簇合官能化有机硅氧烷可配制成热自由基固化粘合剂组合物。
