Abstract: A coating composition has 5-15% by weight of a polymeric binder selected from a polyester polyol, an acrylic polyol, an epoxy, silicone, a silicone hybrid and a fluoropolymer. The composition has 20-40% by weight of microparticles, where the microparticles are made of a polyamide, a polyethylene, a polypropylene, a polyurea, a polyurethane, a polymethyl methacrylate, a polystyrene or mixtures thereof and the microparticles have a mean particle diameter d50 size ranging from 5 ?m to 60 ?m. The composition has 2-12% by weight of nanoparticles, said nanoparticles are made of inorganic oxides with a primary particle size ranging from 5 nm to 50 nm; 0-15% by weight of a crosslinker having reactivity to the polymeric binder; 0-20% by weight of pigments and/or fillers, and 40-80% by weight of an organic solvent.
