Title:
COATING COMPOSITION FOR USE IN SHIP WITH REDUCED FRICTION DRAG UTILIZING GAS-LUBRICATING FUNCTION IN WATER, COATING FILM FORMED FROM SAID COMPOSITION, SHIP COATED WITH SAID COATING FILM, METHOD FOR MANUFACTURING SAID SHIP, METHOD FOR PREDICTING SAID FRICTION DRAG REDUCTION EFFECT, DEVICE USED FOR PREDICTION OF SAID FRICTION DRAG REDUCTION EFFECT, AND FRICTION DRAG REDUCTION SYSTEM FOR USE IN SAID SHIP WITH REDUCED FRICTION DRAG
Document Type and Number:
WIPO Patent Application WO/2014/084324
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a ship with a reduced friction drag, which can keep the affinity for a gas such as air in water for a long period, has a high fluid friction drag reduction effect, is economically advantageous and has little influence on the environment; a coating composition which enables the formation of a coating film that can keep the affinity for a gas such as air in water for a long period, has a friction drag reduction effect and can exhibit a stain-proof function under stream or under static conditions; and others. The present invention relates to a coating composition which enables the formation of a coating film having a specified static in-water bubble contact angle and a specified in-water bubble roll (slip) angle and can be used for a ship with a reduced friction drag utilizing a gas-lubricating function in water. The present invention also relates to a stain-proof coating composition which comprises a specific organopolysiloxane (A), a specific organosilane (B) and a specific hydrophobic material (C) in specified amounts and can be used for a ship with a reduced friction drag utilizing a gas-lubricating function in water.
