Abstract

PURPOSE: To obtain the titled composition excellent in expansion ratio and workability, by incorporating an isocyanate group-containing compound and pyrogenic silica with a specified composition capable of forming a polyorganosiloxane foam by means of hydrogen evolution.
CONSTITUTION: The titled composition is prepared by blending 100pts.wt. polydiorganosiloxane having molecular terminals replaced with silanol groups and viscosity (25°) of 5×106W2×105 cSt, 0.1W50pts.wt. organosilicon compound having 2 or more organoaminoxy groups connected to silicon atoms, 0.1W50pts.wt. polyorganosiloxane having at least 10% (based on silicon atoms) Si-H bonds (at least 2 bonds), 1W30pts.wt. pyrogenic silica (e.g., a pyrolysis product of organochlorosilane) and 0.005W10pts.wt. organic compound having isocyanate groups (e.g. hexamethylene diisocyanate).
