KIT FOR PREPARING WATER-SEALING MATERIAL FOR ELECTRICAL WIRE WATER-SEALING MATERIAL FOR ELECTRICAL WIRE, WATER-SEALING MEMBER, WATER-SEALED ELECTRICAL WIRE, AND WATER-SEALING METHOD

摘要

A radiation-curing type water-sealing material for electrical wire, for water-sealing of an exposed part of a conductor obtained by removing a part of coating material from an electrical wire comprising a conductor and the coating material for coating the conductor or a gap between plural electrical wires in a cable comprising plural electrical wires each having a conductor and a coating material for coating the conductor, comprising the following components (A) to (D) : (A) 5 to 50% by mass, of a urethane (meth) acrylate; (B) 30 to 90% by mass of a compound having one ethylenically unsaturated group; (C) 0.01 to 10% by mass of a radiation polymerization initiator, and (D) 0.1 to 5% by mass of an organic peroxide, based on 100% by mass of the whole volume of the composition.
