摘要

The present invention provides a ship with reduced frictional resistance that has a long-term affinity for air such as air in water, has a large fluid frictional resistance reduction effect, is economical, and has little impact on the environment. A coating composition that can maintain a long-term affinity with air or other gases in water, has an effect of reducing frictional resistance, and can form a coating film that has an antifouling function even during navigation or at rest. It is an issue to provide. The present invention relates to a coating composition for use in a ship with reduced frictional resistance utilizing a gas lubrication function in water, which can form a coating film having a specific static underwater bubble contact angle and a specific underwater bubble rolling (slip) angle. is there. In addition, the present invention provides a gas lubrication function in water comprising a specific amount of a specific organopolysiloxane (A), a specific organosilane (B), and a specific hydrophobic material (C). It is an antifouling paint composition used for a ship with reduced frictional resistance.
