| 摘要 |
The present invention relates to a coating material having heat reflection properties and excellent oleophobicity/hydrophobicity, which is suitable as a coating for interior walls and exterior facades. It comprises the following constituents: a) at least one silane of the formula (I)<paragraph lvl="0"><in-line-formula>XaRbSiR14-a-b (I)</in-line-formula> 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) 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, and c) a solvent and/or dispersion medium, and is characterized in that 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.
