Self-cleaning coating composition

A coating composition, comprising:

• a) 5-15% by weight of a polymeric binder selected from the group consisting of a polyester polyol, an acrylic polyol, an epoxy, a silicone, a silicone hybrid, and a fluoropolymer;
• b) 20-40% by weight of microparticles, wherein the microparticles are made of a polyamide, a polyethylene, a polypropylene, a polyurea, a polyurethane, a polymethyl methacrylate, a polystyrene, and mixtures thereof, wherein the microparticles have a mean particle diameter d50 size ranging from 5 μm to 60 μm;
• c) 2-12% by weight of nanoparticles, wherein the nanoparticles are made of inorganic oxides with a primary particle size ranging from 5 nm to 50 nm;
• d) 0-15% by weight of a crosslinker having reactivity to component a);
• e) 0-20% by weight of pigments and/or fillers;
• and
• f) 40-60% by weight of an organic solvent,
• wherein the sum of components a) to f) of the composition equals 100% weight.
