COATING COMPOSITIONS WITH PHOTOCATALYTIC ACTIVITY

摘要

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.
