Abstract
PURPOSE: To prepare the titled composition giving a cured product having excellent rubber elasticity, electrical insulation, etc., by compounding a hydrogenated polyhydroxybutadiene polymer as the base component with specific isocyanate-based curing agent and a flame-retardant such as hydrated alumina, etc.
CONSTITUTION: The objective composition is prepared by compounding (A) 100pts.wt. of a hydrogenated polyhydroxybutadiene polymer as the base component with (B) a flame-retardant comprising 60W150pts.wt. of hydrated alumina and 5W30pts.wt. of magnesium hydroxide and (C) a curing agent comprising an isocyanate compound of formula I (R1WR3 are lower alkyl; n is 1W4), e.g. 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl isocyanate, and 2,4-toluene diisocyanate dimer of formula II.
EFFECT: Low viscosity and long pot life.
USE: For molded impedance transformer or power transformer, etc.
