【発明の名称】被覆酸粒子を含む組成物およびその組成物を含む粉末塗料
Document Type and Number:
Japanese Patent JP3053438
Kind Code:
B2
Abstract:
An acid composition comprises a polyvalent carboxylic acid solid particle coated with a polymer. The acid composition may function as a cross-linking agent in a powder coating, which also includes a resin. The resin and the polymer of the acid composition may be the same, or they may be different. The mean particle size of the coated acid solid particles is in the range of 0.5 to 50 micrometers. When used in a powder coating, such coated solid particles reduce or eliminate sublimation of the acid cross-linking agent from the powder coating during the curing step. In addition, these coated solid particles increase the storage shelf-life of the powder coating in which they are used. Such coated particles also improve the flow characteristics of the powder coating during curing thereof and the gloss and surface quality of the final cured coating.
