  • Patent number: 4799360
    Abstract: The invention discloses a method of binding a metal, capable of forming a metal hydride, to a surface. The invention also includes a composition which can be applied to a surface, and which can be repeatedly hydrided and dehydrided. According to the invention, a metal capable of forming a metal hydride is pulverized, mixed with a binder, and coated onto a support. The choice of the binder is an important aspect of the invention. Because of the expansion and contraction of the metal, due to the hydriding and dehydriding, the binder must be quite elastic. The binder must also be permeable to hydrogen, and must be heat stable. Silicone rubbers meet these requirements, and can be used as binders.
