PURPOSE:To obtain the subject composition containing a liquid polybutadienepolyol, etc., having excellent flame resistance, flexibility, resistance to wet heat and reliability and useful for a control substrate for electric washing machine. CONSTITUTION:The objective composition containing (A) 100 pts.wt. liquid polybutadienepolyol (preferably having 1000-3000 number-average molecular weight), (B) a bifunctional castor oil transesterified product, preferably of 60-90 pts.wt., (C) a phosphoric acid ester such as triphenyl phosphate, preferably of 80-100 pts.wt., (D) hydrated alumina, preferably of 400-500 pts.wt., (E) monofunctional castor oil transesterified product, preferably of 10-20 pts.wt. and (F) a polyisocyanate such as tolylene diisocyanate (the blend ratio is preferably 0.8-1.3 equivalent based on total amount of hydroxyl group of these components A to C). Furthermore, the composition is cast onto a control substrate for electric washing machine and cured to provide the objective moisture-proof insulated control substrate for electric washing machine. |
