Embodiment

[0088] Hereinafter, the present invention will be described in more detail by way of examples and comparative examples.

[0089]

[0090] 2652 g of neopentyl glycol as an alcohol component of the polyester resin, 3966 g of isophthalic acid as a carboxylic acid component, and 4.7 g of tetra-n-butyl titanate as a reaction catalyst were charged into a mixture equipped with a stirring device, a heating device, a thermometer, In a stainless steel reaction vessel with a fractionation device and a nitrogen introduction tube, polycondensation reaction was carried out at 250° C. for 16 hours while stirring under a nitrogen atmosphere, and the reaction was terminated when a predetermined hydroxyl value was reached to obtain a polyester resin A.

Abstract

The present invention relates to a layer separation type powder coating material composition which has good weather resistance and is reduced in the production cost. The present invention specifically relates to a powder coating material composition which contains a fluororesin containing a hydroxyl group or a carboxyl group, a polyester resin containing a hydroxyl group or a carboxyl group, and a curing agent that is selected from the group consisting of beta-hydroxyalkyl amide, triglycidyl isocyanurate and isocyanate compounds, and which is capable of forming a coating film that comprises a fluorine coating film layer and a polyester coating film layer.

Description

technical field [0001] The present invention relates to a powder coating composition and a method for producing the powder coating composition, and particularly to a powder coating composition capable of forming a coating film including a fluorine coating layer and a polyester coating layer. In addition, this powder coating composition may also be called a layer separation type powder coating composition. Background technique [0002] In recent years, environmental problems on a global scale, such as global warming, ozone depletion, and acid rain, have increased dramatically, and countermeasures against environmental pollution have been called for internationally. Various regulations have been imposed from the viewpoint of environmental protection in conjunction with this. Among them, the release of organic solvents (especially volatile organic compounds VOC) into the atmosphere has become a serious problem, and the tendency to strengthen VOC regulations and the dynamics of ...
