Abstract

PURPOSE: To produce a foam whose film thickness is easily controlled and which provides smooth surfaces, by mechanically foaming an organic isocyanate compound and a hydroxyl group-containing organic compound in the presence of an oxyalkylene group-containing organopolysiloxane.
CONSTITUTION: The foam of the purpose is obtained by converting, to the state of foam, an organic isocyanate compound and a hydroxyl group-containing organic compound is the presence of an oxyalkylene group-containing organopolysiloxane represented by formula I, wherein Ga, Gb and Gc are each methyl or an oxyalkylene of formula II, (in which R is H, a lower alkyl, an acyl, 0=j<0, 0=k≤15, 0=i≤15 and k+1=1W15) 0=m≤10, 0=n≤30, when Ga, Gb and Gc all are oxyalkylene groups, 0=m≤10, 0=n≤20, when Ga is an oxyalkylene group and Gb and Gc are methyl groups, m≤10, 0=n≤20 and when Ga and/or Gc are oxyalkylene groups and Gb is methyl group, 0=m+n≤30, by a mechanical means.
