Disclosed are curable, solvent or solventless, liquid or solid (powder) film forming polymer compositions, comprising a curable polymer, at least one UV stabilizer and a polymeric hindered amine stabilizer which is the reaction product of
with epichlorohydrin
and having a molecular weight from 500 to 50,000; with substituents as defined in claim 1. The coatings are useful on wood, plastic or metal, for example in mono-coats and electro-coating (e-coating) systems, stoving lacquers, as for durable automobile finishes, 1K or 2K, low solids, medium solids, and high solids and particularly low level VOC coatings.
本发明公开了可固化、无溶剂或无溶剂、液态或固态(粉末)成膜聚合物组合物,该组合物包含一种可固化聚合物、至少一种紫外线稳定剂和一种聚合物受阻胺稳定剂,受阻胺稳定剂是以下物质与环氧氯丙烷反应的产物
与环氧氯丙烷的反应产物
其分子量在 500 至 50,000 之间;其取代基如权利要求 1 所定义。这些涂料适用于木材、塑料或金属,例如用于单涂层和电涂层(e-coating)系统、除污漆(如用于耐用汽车面漆)、1K 或 2K、低固含量、中固含量和高固含量,特别是低挥发性有机化合物(VOC)涂料。
