Title:
FISHING NET ANTIFOULING COATING COMPOSITION AND FISHING NET, FISHING NET GEAR, OR UNDERWATER STRUCTURE HAVING ON SURFACE THEREOF ANTIFOULING COATING FILM FORMED USING SAID COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/120360
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a fishing net antifouling coating composition capable of maintaining a suitable chemical release amount from the initial phase of immersion in water, sustaining an antifouling effect over an extended period of time, and persistently exhibiting exceptional antifouling performance against organisms adhering to fishing nets over an extended period of time. Provided according to the present invention is a fishing net antifouling coating composition containing a copolymer (A), a silicone oil (B), and an antifouling agent (C), wherein the copolymer (A) is a copolymer of a monomer (a) represented by general formula (1) and an ethylenically unsaturated monomer (b) other than the monomer (a), the monomer (a) includes a compound for which n in general formula (1) is greater than or equal to 2, and the silicone oil (B) is a modified silicone oil having a hydrophilic-lipophilic balance (HLB value) of 0.5-9.
