Abstract
The flowability of foamable compositions comprising a hydroxyl-containing polyorganosiloxane, a polyorganosiloxane containing silicon-bonded hydrogen atoms, a platinum catalyst and a catalyst inhibitor is eliminated by including in the composition a solid filler exhibiting a mean particle size of one micron or less and either (1) organosilicon compound containing at least 0.5% by weight of carboxyl groups or silicon-bonded hydroxyalkyl groups, or (2) a partially esterified polyfunctional alcohol. In addition, the pot life of the composition is increased without adversely affecting the structure of the cured foam or the adhesion of the foam to various substrates.
