<P>PROBLEM TO BE SOLVED: To provide a material for a gasket having excellent leak resistant performance under room temperature condition and under low temperature condition and capable of suppressing increase in surface adhesion properties even after the gasket is left under high temperature condition. <P>SOLUTION: In the material for the gasket including an energy ray curing liquid oligomer (A) having a (meth)acryloyl group and a (meth)acrylate monomer (B) represented by general formula (1), the mixing ratio [(A):(B)] of the component (A) and component (B) is 97:3 to 30:70 by mass and 3 to 20 pts.mass silica is contained to 100 pts.mass total amount of the component (A) and component (B). (in formula, R<SP POS="POST">1</SP>denotes a hydrogen atom or a methyl group, R<SP POS="POST">2</SP>denotes a 4-18C chain type saturated aliphatic hydrocarbon group, W denotes an ethylene group or a propylene group, and n denotes an integer of 0 to 2). <P>COPYRIGHT: (C)2013,JPO&INPIT |
