  • Method for coating a surface
    Patent number: 6316057
    Abstract: Metal surfaces, metal-oxide surfaces, metal-salt surfaces, silicon-comprising surfaces and/or high-molecular-weight aquoxide-comprising organic surfaces are coated. The coating is carried out with a reagent having a reactive group chosen from Si—H, Sn—H, and Ge—H. The reagent is applied in liquid, pasty, or solid form to the surface that is to be coated. Furthermore, the coating reaction requires the presence of an activator. A platinum metal in form of a compound or in metallic form is used as activator.
