FIELD: chemistry.
SUBSTANCE: invention relates to a coating composition, a coating which contains such a composition, an article and a method of coating a substrate. The coating composition contains a copolymer obtained from a reaction mixture containing: ethylenically unsaturated hydrolysable silane, ethylenically unsaturated polyoxyalkylene, ethylenically unsaturated fluorinated polyether, an initiator and a chain-transfer agent. The coating contains a curable sol-gel dispersion and a coating composition. The article has a substrate and a cured coating on at least one surface of the substrate, where the cured coating is a curable composition which contains a curable sol-gel dispersion and a coating composition. The method of coating the substrate comprises steps of: providing a substrate, providing a curable coating composition which contains a curable sol-gel dispersion and a coating composition, applying a coating from the curable coating composition on at least part of the substrate and curing the coating.
EFFECT: obtaining a coated substrate which provides low surface energy to make cleaning easier, having low degree of picking up cleaning waste.
