<p><P>PROBLEM TO BE SOLVED: To prevent yellowing due to penetration of sulfur components to a surface skin layer from a gasket body, in gaskets comprising the gasket body formed of a valcanized rubber material and a resin surface skin layer formed integrally with the surface layer part of the gasket body, and being fitted into joints between outer wall panels of a building. <P>SOLUTION: In the gasket 11 comprising the gasket body 4 and the surface skin layer 5 formed in the surface layer part 3 of the gasket body 4 through an adhesive layer 12, the adhesive layer 12 includes an intermediate base material layer formed of a metal foil for blocking the penetration of sulfur components from the gasket body 4 to the surface skin layer 5 and an outer layer comprising polyethylene to be applied to both sides of the intermediate base material layer, and at the same time as when it is valcanized by heating after extrusion molding, the polyethylene melts and adheres the intermediate base material layer, the gasket body 4 and the outer layer. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
