Ship, underwater structure which is coated with a coating film organopolysiloxane antifouling coating film for tie coat, and composite coating film,

摘要

A tie coat formed on the surface of the undercoating film or substrate prior to forming the organopolysiloxane-based antifouling coating film, (b1) said tie coat, a condensable functional group in the "both ends of the molecule an organopolysiloxane having ", and or /, (b2) or under heating," above-mentioned (b1), and extender pigments selected from the group consisting of barium sulfate silica, calcium carbonate, talc, mica, clay, kaolin and tie coat which is formed by the moisture-curing organopolysiloxane composition comprising the non-heating, a curable composition, "formed by contact treatment. On the tie coat surface, and three-part Oruganopori which is formed main agent containing (c1) above, a curing accelerator component containing (c3) a metal compound and a curing agent component comprising a condensate thereof, or (c2) tetraalkoxy silicate composite coating film formed a finish coat consisting of a siloxane-based curable composition. composite coating film Kyubo Kitananurimaku to (G) surface, were successively formed epoxy sealer coat, said tie coat, the finish coat. Tie coat capable of forming a composite coating film having excellent interlaminar adhesion is provided. In addition, it is preferably formed on the surface of the substrate, an undercoat paint film, such as Kyubokitana coating, excellent stain-interlayer adhesion strength, defense, the composite coating, submerged marine structures and the outer surface of the vessel It is suitable as a coating of water supply and drainage path and the like part, of a nuclear power plant.
