应用于塑料和涂料中的有机颜料

在生产塑料时,选择正确的颜料取决于颜料的分散能力,迁移特性,热稳定性,光稳定性以及价格。这些性能与颜料的浓度,塑料的厚度,助剂的使用有很大的关系。当颜荆粉末与高分子树脂混合,在溶剂中高速分散,制成涂料。所有的涂料者含有四个主要成分：颜料、高分子/树脂连接剂、溶剂、助剂。此文阐述有机颜料在塑料与涂料中的性能并且总合其在商业上的一些应用。

Organic pigments used in plastics coatings

It is important to select proper pigments during the plastics production. We must understand pigment dispersibility, migration tendency, heat stability, light fastness and price. This information will decide color＇s concentration, plastics thickness, additive usage.The production of paint is made by mixing pigment powder, polymeric resin in solvent and by agitating at high speed to disperse the paint. All coatings contain four key ingredients： pigment, polymeric resin/binder, solvent, additive. This article describes the performance of organic pigments in plastics and in coating and lists their application.
