Document Type and Number:
WIPO Patent Application WO/2012/176809
Kind Code:
A1
Abstract:
[Problem] To provide an antifouling paint composition which, while reducing volatile organic compounds (VOCs), has good coatability at low temperatures as well as at room temperature, and which is capable of forming coating films having excellent mechanical strength and good long-term antifouling. [Solution] A two-component hydrolysis-type antifouling paint composition which comprises a first liquid component containing a reaction mixture (A) containing a polyester resin (a3) obtained by polycondensation of an acid component (a1) and a polyvalent alcohol component (a2), and an acetoacetyl group-containing compound (B), and a second liquid component containing zinc oxide (C), and is characterized in that the acid value and hydroxyl value in the solid component of the reaction mixture (A) are 50-200 mgKOH/g and 100 mgKOH/g or less, respectively, and in containing substantially no copper or copper compounds.
