    • A thermosetting powdery coating composition which comprises, in admixture: (A) from 40 to 98 parts by weight of a fluorine-containing copolymer, which is a copolymer of a fluoroolefin and a comonomer having a crosslinkable reactive group, e.g., hydroxy, carboxyl, amino and glycidyl groups, containing at least 10% by weight of fluorine and having an intrinsic viscosity of 0.05-2 dl/g (30.degree. C., tetrahydrofuran), a glass transition temperature of 30.degree.-120.degree. C. and a weight loss by heating which does not exceed 2% and (B) from 60 to 2 parts by weight of a curing agent capable of forming crosslinks by reacting with the crosslinkable reactive groups in (A), except for the composition wherein (A) is a hydroxyl group and a weight loss by heating which does not exceed 2% and (B) is a blocked isocyanate compound. The powdery coating composition is excellent in the dispersibility of pigments and efficiency in the coating works therewith and capable of giving a coating film having improved adhesion to a substrate surface, surface luster, impact resistance and insusceptibility to staining.
    • 一种热固性粉末涂料组合物,其包含:(A)40至98重量份的含氟共聚物,其为氟代烯烃和具有可交联反应性基团的共聚单体的共聚物,例如羟基,羧基, 氨基和缩水甘油基,其含有至少10重量%的氟,特性粘度为0.05-2dl / g(30℃,四氢呋喃),玻璃化转变温度为30-120℃,重量 除了不超过2%的加热损失,(B)60至2重量份的能够通过与(A)中的可交联反应性基团反应形成交联的固化剂,除了其中(A)为 羟基,加热失重不超过2%,(B)为封端异氰酸酯化合物。 粉末涂料组合物在颜料的分散性方面优异,并且在其涂料中效率高,并且能够提供对基材表面具有改善的粘附性的涂膜,表面光泽,耐冲击性和不可感染性。

    • A patterned decorative material is prepared by a method which comprises applying a thermosetting powder coating material to a base plate; melting of the thermosetting powder coating material by heating; simultaneously embossing the coating layer and the base plate while the melted thermosetting powder coating material has a gel fraction formed by a hardening reaction of 0 to 75 weight percent; and further heating to form a hardened coating on the base plate. The patterned decorative material is excellent in appearance, corrosion resistance, weathering resistance and abrasion resistance and is free from the defects of conventional steel plates coated with polyvinyl chloride and the like, such as formation of craze and loss of luster.
    • 图案化装饰材料通过包括将热固性粉末涂料施加于基板的方法制备; 通过加热熔化热固性粉末涂料; 同时对涂层和基板进行压花,同时熔化的热固性粉末涂料具有通过0至75重量%的硬化反应形成的凝胶分数; 并进一步加热以在基板上形成硬化涂层。 图案化的装饰材料的外观,耐腐蚀性,耐候性和耐磨性优异,并且不存在涂覆有聚氯乙烯等的常规钢板的缺陷,例如形成热潮和失光。

    • A patterned decorative material is prepared by a method which comprises application of a thermosetting powder coating material to a base plate; melting of the thermosetting powder coating material by heating; embossing of the coating layer alone while the melt thermosetting powder coating material has a gel fraction formed by a hardening reaction of 15 to 75 weight percent; and further heating to form a hardened coating on the base plate. The prepared patterned decorative material is excellent in appearance, corrosion resistance, weathering resistance and abrasion resistance and free from the defects of conventional steel plates coated with polyvinyl chloride and the like, such as formation of craze and loss of luster.
