Abstract:
An improvement in a gasket used between confronting surfaces of structural components, the gasket having at least one thin plate that is made therein with fluid-communication holes,the improvement comprising an adhesive susceptible to plastic deformation attached around the fluid communication holes on both opposite surfaces of the at least one thin plate, which faces the confronting surfaces, to provide mating areas where the adhesive comes into engagement with the confronting surfaces thereby restraining relative displacement between the opposite surfaces of the at least one thin plate and the confronting surfaces of the structural components in favor of at least plastic deformation of the adhesive and also making the gasket as a whole solid state to establish a sealing to keep a fluid against leakage out of the confronting surfaces past any clearance between the confronting surfaces,and wherein the adhesive is composed of a liquid urethane polymer having a viscosity capable of keeping form retention when being subject to stress at an ambient temperature, the adhesive exhibiting water resistant, oil resistant, heat resistant and non-curing properties at a temperature condition up to 200.about.300.degree. C., and the adhesive being attached to the opposite surfaces of the at least one thin plate and,when being squeezed between the confronting structure components, subjected to plastic deformation to be held at sealing areas in favor of not only adhesiveness of the deformed adhesives in themselves with the opposite surfaces and the confronting surfaces but also joint retention characteristics of the adhesive.
