Abstract
The invention relates to a composition for producing abrasion-resistant and alkali-resistant layers or moulded bodies having a low-energy surface, said composition comprising a) a hardenable binder system containing at least one organic polymer or oligomer comprising at least one functional group, or a precursor thereof, b) at least one fluorine-containing polymer or oligomer containing at least one functional group that can react with a functional group of the binder system, and c) inorganic particles, and to the products thus obtained. The coatings and moulded bodies obtained are especially suitable for surfaces to be kept clean.

A composition for the production of an abrasion-resistant and alkali-resistant coating or shaped body with a low-energy surface, comprising
- (a) a curable binder system comprising at least one organic polymer or oligomer with one or more functional groups or a precursor thereof,
- (b) at least one fluorinated polymer or oligomer having at least one functional group which is reactive with a functional group of the binder system, and
- (c) one or more types of inorganic particles.
A composition for the production of an abrasion-resistant and alkali-resistant coating or shaped body with a low-energy surface, comprising
- (a) a curable binder system comprising one or more of an epoxy resin, a polyol, a polyisocyanate, a polyester, a polyacrylate, a polyamine, a polyamide, a polyimide, a polybenzimidazole and precursors thereof,
- (b) at least one fluorinated polymer or oligomer having at least one functional group which is reactive with a functional group of the binder system and comprises one or more of a —SO3H group, a —PO3H group, an amino group, a carboxyl group and a hydroxyl group, and
- (c) one or more types of inorganic particles which comprise at least one compound selected from one or more of oxides, nitrides, carbides, carbonitrides, suicides and borides and have a mean particle diameter of from 0.1 μm to 100 μm.
