Title (EN) COATING COMPOSITION AND COATED OBJECT
(FR) COMPOSITION DE REVÊTEMENT ET ARTICLE REVÊTU
(JA) 塗料組成物および塗装体
Abstract:
(EN) Provided are: a coating composition capable of forming hardened coating films that are excellent in terms of processability and weatherability; and a coated object which includes a hardened coating film formed from the coating composition. This coating composition comprises a hydroxylated fluoropolymer having a hydroxyl value of 5-100 mg-KOH/g, a hydroxylated (meth)acrylate-based polymer having a glass transition temperature of 15-70ºC, and at least one hardener selected from the group consisting of isocyanate-based hardeners, blocked-isocyanate-based hardeners, and amino resins. In the coating composition, the absolute value of the difference between the number-average molecular weight of the fluoropolymer and the number-average molecular weight of the (meth)acrylate-based polymer is 5,000 or less.
(FR) L'invention concerne : une composition de revêtement apte à former des films de revêtement durcis qui sont excellents en termes d'aptitude au traitement et de résistance aux intempéries ; et un objet revêtu qui comprend un film de revêtement durci formé à partir de la composition de revêtement. Cette composition de revêtement comprend un fluoropolymère hydroxylé ayant un indice d'hydroxyle de 5 à 100 mg-KOH/g, un polymère à base de (méth)acrylate hydroxylé possédant une température de transition vitreuse de 15 à 70 °C, et au moins un durcisseur sélectionné dans le groupe constitué des durcisseurs à base d'isocyanate, des durcisseurs à base d'isocyanate bloqué, et des résines amino. Dans la composition de revêtement, la valeur absolue de la différence entre le poids moléculaire moyen en nombre du fluoropolymère et le poids moléculaire moyen en nombre du polymère à base de (méth)acrylate est inférieure ou égale à 5 000.
(JA) 加工性および耐候性に優れた硬化塗膜を形成可能な塗料用組成物、および該塗料用組成物から形成された硬化塗膜を有する塗装体を提供する。 本発明の塗料組成物は、水酸基価が5~100mgKOH/gである水酸基を有する含フッ素重合体と、ガラス転移温度が15~70℃である、水酸基を有する(メタ)アクリレート系重合体と、イソシアネート系硬化剤、ブロック化イソシアネート系硬化剤およびアミノ樹脂からなる群から選ばれる少なくとも1種の硬化剤と、を含有する塗料組成物であって、前記含フッ素重合体の数平均分子量と前記(メタ)アクリレート系重合体の数平均分子量との差の絶対値が5000以内である。
