COATING FILM FOR STRUCTURE, COATING MATERIAL SET FOR FORMING COATING FILM, COATING MATERIAL FOR UNDERCOAT LAYER, AND COATING METHOD
An object of the present invention is to provide a coating film which is capable of being peeled off in the shape of sheet to facilitate a coating film removal work, and is less likely to peel even after long periods of use on an underwater structure. Provided is a coating film which comprises an undercoat layer to be bonded to an underwater structure, and an antifouling layer bonded to the undercoat layer, wherein: a 100-gram underwater constant load peeling degree of the coating film is less than 5 (mm/20 mm); a ratio of a tensile breaking strength (N/20 mm) of the coating film to an adhesive force (N/20 mm) of the coating film with respect to the underwater structure, as measured after immersing the coating film in pure water at 60°C for 5 weeks is 1.5 or more; and a 1-mm square cross-cut stretching-caused peeling degree of the antifouling layer with respect to the undercoat layer is 0.05 or less.
