ていた。2. Description of the Related Art Various marine organisms, such as shellfish and algae, adhere to the surface of submerged parts such as marine structures, ships, and seawater intake pipes. Therefore, antifouling paint is applied as a countermeasure. Conventionally, antifouling paints prevent the adhesion of marine organisms by gradually dissolving the antifouling agent component incorporated in the paint from the coating film into seawater, but use a large amount of a toxic antifouling agent. Therefore, there is a risk of polluting seawater in the long run, which may have a bad effect on fish and shellfish. Therefore, non-toxic antifouling paints containing no toxic antifouling agent have been proposed. For example, Japanese Patent Publication No. 60-3
No. 433, JP-B-63-2959, etc. disclose non-toxic antifouling paints comprising a reaction-curable silicone rubber and a bleed component such as silicone oil or liquid paraffin. If the bleed component is added in a large amount to maintain the antifouling performance for a long period of time, the performance cannot be sustained, but the adhesion of the coating film will decrease, and the coating film strength will decrease.

It is produced by, for example, a method of performing an addition reaction with a polyether having a carbon-carbon double bond at a terminal. The polyether-modified silicone oil is blended to give the formed coating film an antifouling function. That is, the polyether-modified silicone oil bleeds on the surface of the coating film, which forms an unstable fluidized layer on the surface of the coating film, and at the same time imparts water repellency to the coating film to exhibit antifouling properties. In addition,

The number average molecular weight is preferably from 1,000 to 50,000.
If the number average molecular weight exceeds 100,000, bleeding tends to be difficult to occur on the surface of the coating film.
