Abstract

The present invention relates to a curable mixture suitable for obtaining “easy-to-clean” properties in the cured mixture, comprising at least one mineral binder, a powder comprising at least one fluoroorganyl-substituted silicon compound encapsulated in a water-soluble polymer, the amount of the silicon compound being 0.001% to 8% by weight, based on the present mixture, and optionally further adjuvants, and also to a process for preparing the mixture and to the use thereof. The invention further relates to a water-redispersible powder and also to a corresponding intermediate for use in the curable mixture in order to obtain “easy-to-clean” properties in the cured mixture. Also claimed, furthermore, is a process for preparing the powder, and the use thereof.
