A coating material for interior walls and exterior facades has heat reflection and oleophobicity/hydrophobicity, properties. The material is either opaque to visible light and/or contains a material which provides opacity. It includes:a) at least one silane of the formula (I)in whichX is a hydrolyzable group,R is optionally substituted alkyl, alkenyl, aryl, alkylaryl or arylalkyl,R<1 >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, andb is an integer from 0 to 2,or a (partial) condensate of this silane,b) at least one infrared-reflecting pigment whose particle size is situated primarily in the range from 1 to 50 mum, andc) a solvent and/or dispersion medium. |
