摘要： A composition for forming a foamed silicone elastomer is disclosed. The composition comprises: A) an organopolysiloxane having at least two silicon-bonded ethylenically unsaturated groups per molecule; B) an organohydrogensiloxane having at least two silicon-bonded hydrogen atoms per molecule; C) a hydrosilylation catalyst; D) a chemical blowing agent; and E) a physical blowing agent. The hydrosilylation catalyst C) is present in a catalytically effective amount. The chemical blowing agent D) has at least one hydroxyl (OH) group, and is present in an amount to provide a OH content >0 and

摘要： A room temperature curable organopolysiloxane composition comprises: (A) an organopolysiloxane having alkoxysilyl-containing groups at both molecular terminals; (B) an organopolysiloxane resin; (C) an alkoxysilane; and (D) a condensation-reaction catalyst. The room temperature curable organopolysiloxane composition exhibits good to excellent storage stability. In addition, the room temperature curable organopolysiloxane composition can form a cured product exhibiting good to excellent mechanical properties.
