Coating film for structure, coating material set for forming coating film, coating material for undercoat layer, and coating method
The purpose of the present invention is to provide a coating film which is removable in a sheet and makes removing easy, and is not susceptible to peeling even when used for a long period of time on an underwater structure. Provided is a coating film that comprises an undercoat layer that adheres to an underwater structure, and an antifouling layer that adheres to the undercoat layer. The degree of peeling of the coating film underwater at a constant load of 100 grams is less than 5 (mm/20mm), and the ratio of the tensile rupture strength (N/20mm) after submersion for 5 weeks in 60°C pure water relative to the adhesive force (N/20mm) with the underwater structure is 1.5 or greater. The degree of stretching and peeling of a 1 mm square crosscut piece of the antifouling layer with respect to the undercoat layer is 0.05 or lower.
