  • Method for producing fluoroalkyl-functionalized silane coatings
    Patent number: 6541563
    Abstract: The invention concerns a method for producing fluoroalkyl-functionalized hybrid polymer coatings with low surface energy and low tendency to become soiled. Organically modified silanes, metal compounds of formula AlR3 or MR4 and at least partially fluorinated organic modified silane serve as components of the coating composition.

  • Coating material and process for the production of functional coatings
    Patent number: 6534187
    Abstract: The invention relates to a process for producing functional coatings with organofunctional silanes, a metal compound and difficultly volatile oxides, in which a) a hydrolytic condensation is performed, optionally in the presence of a condensation catalyst and/or additives, of the following components 1. at least one crosslinkable organofunctional silane, 2. at least one metal compound, 3. optionally at least one non-crosslinkable organofunctional silane and 4. optionally one or more difficultly volatile oxides soluble in the reaction medium; b) that to said hydrolytic condensate is added an organic, crosslinkable prepolymer; and c) the thus obtained coating solution is applied to a substrate and subsequently cured.
