Coating material for multifunctional superphobic layers

Coating material comprising of the following constituent(s):

• a) at least one silane of the formula (I)
• XaRbSiR14−a−b (I)
• in which
• X is a hydrolyzable group,
• R is optionally substituted alkyl, alkenyl, aryl, alkylaryl or arylalkyl,
• R1 is an organic radical which is attached to the silicon via carbon and carries a reactive group,
• a is an integer from 1 to 3, and
• b is an integer from 0 to 2,
• or a (partial) hydrolyzate/condensate of this silane,
• b) at least one infrared-reflecting pigment whose particle size is situated primarily in the range from 1 to 50 μm, and
• c) a solvent and/or dispersion medium, wherein either the pigment is present at least in an amount such that the coating material, following application to a surface, is substantially opaque to light in the visible region and/or a further constituent of the coating material brings about such opacity to light of the coating material.
