Title:
ANTIFOULING COATING COMPOSITION, ANTIFOULING COATING FILM, ANTIFOULING SUBSTRATE, AND METHOD FOR IMPROVING STORAGE STABILITY OF ANTIFOULING COATING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2014/077205
Kind Code:
A1
Abstract:
In one aspect, the purpose of the present invention is to provide an antifouling coating composition that enables the formation of a coating film exhibiting a high antifouling effect on, in particular, slime and having a high strength, good rubber properties, etc., said antifouling coating composition having an appropriate viscosity (i.e., atomizing properties in spraying and coating film surface-leveling properties) and good anti-sagging properties and showing little deterioration in these properties, i.e., having a high storage stability. The antifouling coating composition according to the present invention comprises: (A) a diorganopolysiloxane having at least two silanol groups per molecule; (B) an organosilane having at least two hydrolysable groups per molecule and/or a partially hydrolyzed condensate thereof; and (C) a pyrithione metal salt. The antifouling coating composition can be prepared from a multi-liquid type kit that comprises a component containing the constituents (A) and (C) and another component containing the constituent (B), said components being packaged separately.
