Abstract
A curable composition capable of securing a waiting time after curing starts, and efficiently controlling the relevant waiting time is provided. The curable composition also controls a curing rate after the waiting time to suit the application. A battery module, a battery pack or an automobile comprising a cured product of the curable composition is also provided.
Claims12
A curable composition comprising:
- a polyol, a reaction inhibitor, a catalyst and a thermally conductive filler,
- wherein the reaction inhibitor comprises one or more reaction-inhibitory functional groups of a mercapto group or a phenolic hydroxyl group,
- wherein an amount of the thermally conductive filler is from 70 to 95 weight %, and
- wherein a required time (Vt2) for the curable composition to have a viscosity that is two times of an initial viscosity is 15 minutes or more, wherein the initial viscosity and the viscosity are measured with a Brookfield HB type viscometer at a temperature of 25° C. under conditions of a torque of 90% and a shear rate of 100 rpm, and wherein the initial viscosity is measured at a curing start point.
