Patent ID: 10370546

Abstract:
The object of the present invention is to provide a water/oil-repellent coating composition for forming a film capable of attaining both water/oil repellency and abrasion resistance. The water/oil-repellent coating composition comprises: an organosilicon compound (A) and a metal compound (B), wherein at least one first hydrocarbon chain-containing group and at least one hydrolyzable group are bonded to a silicon atom in the organosilicon compound (A), where in at least one hydrolyzable group is bonded to a metal atom in the metal compound (B), wherein a second hydrocarbon chain-containing group having a length shorter than the length of the first hydrocarbon chain-containing group may be bonded to the metal atom in the metal compound (B), and wherein a molar ratio of the metal compound B) to the organosilicon compound (A) as metal compound (B)/organosilicon compound (A) is not less than 18 and not more than 48.
