Abstract
A sealing agent is filled into gaps between adjacent groups of electric wires and gaps between the groups of the electric wires and an inner peripheral surface of a grommet. The sealing agent is of a two-liquid reactive hardening type and includes a main agent and a hardening agent, the main agent containing a viscosity depressant mixed with hardening accelerators at a predetermined ratio. The sealing agent has a viscosity of 200 cps-500 cps in a grommet-to-wire assembly environment and gels in three to seven minutes. The mixing weight ratio between the main agent and the hardening agent of the sealing agent is set to a range of 5.5:1-1:1. The main agent includes polyether polyol, triethanolamine and dibutyltin dilaurate both used as the hardening accelerators, a low-molecular weight aromatic hydrocarbon used as a viscosity depressant, and an anti-oxidant. The hardening agent includes polyisocyanate.
