Abstract
The present invention relates to a process for preparing coating compositions which comprises condensing a mixture containing (A) at least one silicone resin containing Si-bonded alkoxy groups and, if desired, silanol groups and/or at least one silane and/or siloxane which contains Si-bonded alkoxy groups and, if desired, silanol groups to form a silicone resin, (B) a basic condensation catalyst in an amount sufficient to render this mixture basic, (C) optionally water and (D) optionally an organic solvent. The resultant coating compositions are preferably employed in the form of a solution, emulsion or dispersion.
