    • In one aspect, the invention has an object of providing antifouling coating compositions which have high resistance to fouling, in particular, fouling by slime, can form coating films with excellent properties such as strength and rubber properties, exhibit appropriate viscosity (sprayability and coating film surface leveling properties during spray coating) and sagging resistance, and have high storage stability suppressing deteriorations of these properties. To achieve the object, the invention provides an antifouling coating composition including (A) a diorganopolysiloxane having at least two silanol groups in the molecule, (B) an organosilane and/or a partial hydrolyzate condensate thereof having at least two hydrolyzable groups in the molecule, and (C) a pyrithione metal salt. The antifouling coating composition can be prepared from a kit in the form of a multiple-component system including respective packages of a component including the component (A) and the component (C), and a component including the component (B). In the (kit for the preparation of the) antifouling coating composition, the pyrithione metal salt (C) functions as an effective ingredient for achieving excellent antifouling properties, in particular, anti-sliming properties, and also as an effective ingredient for improving storage stability.
    • 一方面,本发明的目的在于提供一种抗污垢性高,特别是粘泥污垢的防污涂料组合物,可以形成具有优异性能如强度和橡胶性能的涂膜,显示适当的粘度(喷涂性和涂膜 喷涂时的表面平整性)和下垂阻力,并且具有高的储存稳定性,抑制这些性能的劣化。 为了达到上述目的,本发明提供一种防污涂料组合物,其包含(A)分子中具有至少两个硅烷醇基的二有机聚硅氧烷,(B)分子中具有至少两个可水解基团的有机硅烷和/或其部分水解产物缩合物 ,和(C)吡啶硫酮金属盐。 防污涂料组合物可以由包含组分(A)和组分(C)的组分的相应包装的多组分体系形式的试剂盒和包含组分(B)的组分制备。 在制备防污涂料组合物的试剂盒中,吡啶硫酮金属盐(C)用作实现优异的防污性能,特别是抗纤维化性能的有效成分,并且作为提高储存稳定性的有效成分 。
