摘要

An object of the present invention is to provide a frictional resistance reducing vessel which is economical and has little influence on the environment because the gas affinity of air or the like in water continues to be maintained over a long period of time for a large effect of reducing fluid friction resistance, And which is capable of forming a coating film having an antifouling function even under a standing condition even during a running under the influence of friction resistance. The present invention is a coating composition for use in a frictional resistance reducing vessel that utilizes a gas lubrication function in water, capable of forming a coating film having a specific static bubbling contact angle underwater and a specific underwater bubble roll (slip) angle. Further, the present invention relates to an antifouling coating for a friction reducing abatement vessel using a gas lubrication function in water, comprising a specified amount of a specific organopolysiloxane (A), a specific organosilane (B) and a specific hydrophobic material (C) Coating composition.
