The invention relates to a composition for coating walls, façades or similar. The inventive composition comprises at least one binder which has an absorbance (Kubelka-Munk function F(R8)) of less than 0.8, especially less than 0.5, at least at one absorption wavelength ranging between 380 and 500 nm, particularly between 400 and 450 nm, and at least one photocatalytically active substance that has an absorbance (Kubelka-Munk function F(R8)) exceeding 0.005, above all exceeding 0.01, and most preferably of 0.2 or more at said absorption wavelength. Also disclosed are a method for producing said composition as well as the use of the composition.
L'invention concerne une composition permettant de recouvrir des murs, façades ou équivalent. Cette composition contient au moins un liant qui, à au moins une longueur d'onde d'absorption de la plage comprise entre 380 et 500 nm, notamment de la plage comprise entre 400 et 450 nm, a une absorbance (fonction Kubelka-Munk F(R¿8?)) inférieure à 0,8, notamment inférieure à 0,5 et au moins un moyen d'action photocatalytique qui, à ladite longueur d'onde d'absorption, a une absorbance (fonction Kubelka-Munk F(R¿8?)) supérieure à 0,005, notamment supérieure à 0,01, de préférence 0,02 minimum. L'invention concerne également un procédé permettant de produire la composition et l'utilisation de cette composition.
