A process for coating surfaces by hybrid polymer materials and the coating solutions and compositions used in this process are described.

Process for coating surfaces using hybrid polymer materials

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 AlR or MR and at least partially fluorinated organic modified silane serve as components of the coating composition.

Method for producing fluoroalkyl-functionalized silane coatings

The invention relates to varnished metal wires with one or more electrically insulating varnish coatings, at least one of the electrically insulating varnish coatings representing an organically modified silicic acid (hetero) polycondensate, which has been obtained by partial or total hydrolytic condensation of one or more hydrolytically condensable compounds of silicon and if necessary other elements from the group B, A1, P, Sn, Pb, the transition metals, the lanthanides and actinides, and/or from precondensates derived from the abovenamed compounds, if necessary in the presence of a catalyst and/or of a solvent by the action of water and moisture.

Enamelled metallic wires

The invention relates to a method of reducing lead release from lead crys glass by applying a coating manufactured by application and hardening of a coating material containing a hydrolytic condensation product comprising a cross-linkable organofunctional hydrosilicon, a metal compound and an organic prepolymer cross-linkable with this hydrolytic condensate.
