Abstract
PURPOSE: To provide the titled composition curable at room temp., having excellent insulating characteristics, humidity resistance, and adhesivity, and suitable for the sealing resin of electronic parts, by compounding a mixed polyol obtained by adding castor oil to a specific ester compound with an isocyanate compound as a curing agent.
CONSTITUTION: The objective composition is composed of (A) a mixed polyol obtained by mixing (i) 100pts.wt. of an ester compound prepared by reacting 1 mole of a dibasic acid of formulaIor formula II (n is 5W20; R is lower alkyl such as CH3, C2H5, etc.) with 2W2.5mol of a dihydric alcohol such as ethylene glycol with (ii) 50W250pts.wt. of castor oil, and (B) an isocyanate compound having ≥2 isocyanate groups in the molecule (e.g. diphenylmethane diisocyanate) as the curing agent of the component (A).
