Abstract
This composition comprises (A) an organopolysiloxane having at least two SiOH groups in its molecule, (B) an organopolysiloxane having at least two SiH groups in its molecule, (C) a platinum family metal catalyst, and (D) a hydroperoxide. By using the hydroperoxide as a catalyst-retarding agent in cure reaction of a dehydrogenation system in which hydrogen is a foaming agent, this composition has a long pot life and can be cured and foamed to produce a foamed cured product in the form of a sponge having uniform cells.
