Embodiment

[0286] Hereinafter, although an Example demonstrates this invention more concretely, this invention is not limited to these Examples.

[0287] Hereinafter, curable organopolysiloxane (A) may be referred to as "(A) component", pyrithione salt (B) may be referred to as "(B) component", and titanium oxide (C) may be referred to as "( C) Ingredients", etc.

[0288] [Manufacture of Ether Group-Containing Polymer (F) Solution]

[0289]

[0290] The reaction was carried out under normal pressure and nitrogen atmosphere. In a reaction container equipped with a stirrer, a reflux cooler, a thermometer, a nitrogen introduction tube, and a dropping funnel, 42.86 g of methyl amyl ketone was charged, and heated while stirring until the inner temperature reached 100°C. While keeping the temperature of methyl amyl ketone in the reaction vessel within the range of 100±5°C, 20 g of NKEster AM-90G, 80 g of isobutyl acrylate, 2,2'-even A mixture consisting of 4 g of nitrogen bis(2-methylbuty...

Abstract

The object of the present invention is to provide an organosiloxane-based antifouling coating composition containing a pyrithione salt, which can form an antifouling coating film that does not decrease in antifouling properties even when exposed to an environment affected by sunlight . The antifouling paint composition is characterized in that it is an organopolysiloxane-based antifouling paint composition containing a curable organopolysiloxane (A), a pyrithione salt (B) and titanium oxide (C), Titanium oxide (C) is surface-treated with a compound containing at least one selected from silicon compounds (C1), zirconium compounds (C2), and zinc compounds (C3).

Description

technical field [0001] The present invention relates to an antifouling coating composition, an antifouling coating film using the antifouling coating composition, a substrate with an antifouling coating film, a manufacturing method thereof, and an antifouling method. Background technique [0002] In order to prevent adhesion of aquatic organisms to ships, underwater structures, etc., antifouling coating films formed of organopolysiloxane-based antifouling coating compositions are widely used. In particular, in recent years, studies have been actively conducted to exert a high antifouling effect on microorganisms such as mucus having a coating film of bacterial secretions by combining a physiologically active antifouling agent with the organopolysiloxane-based antifouling coating composition. In terms of performance, among antifouling agents, pyrithione salts are particularly useful for exhibiting excellent antifouling properties over a long period of time. In addition, in o...
