An antifouling coating composition having superior antifouling properties and stability over an extended period of time, said composition comprising

Antifouling coating composition

This invention provides a novel antifouling paint which has excellent storage stability for a long period of time and which affords a coated film having antifouling properties for a long period of time. The paint comprises two components, Component A and Component B, said Component A and said Component B being in separate packages which are mixed before application, wherein Component A contains organotin polymer as antifouling ingredient, and wherein Component B comprises vehicle resin and copper antifoulant.

Two component antifouling paint

A powder coating composition for electrodeposition which comprises powdery particles having 0.1 to 50 microns particle size wetted with an organic solvent having a boiling point of 50.degree. to 250.degree. C in a range of 5 to 100 parts by weight per 100 parts by weight of the powdery particles in said powder coating composition and dispersed in an aqueous medium containing a surface active agent of 0.05 to 5 parts by weight per 100 parts by weight of the powdery particles in said powder coating composition to be dispersed, in which said organic solvent does not dissolve the organic high molecular weight compound in said powder coating composition and is scarcely soluble with said aqueous medium which is water or a mixture of water and water soluble organic solvents.
