柔韧性羧端基不饱和聚酯粉末涂料的研制

Preparing and Researching of the Flexible End-carboxy Unsaturated Polyester Powder Coatings

本文研制了粉末涂料用柔韧性羧端基不饱和聚酯树脂及其相应的环氧树脂固化的柔韧性不饱和聚酯粉末涂料，讨论了树脂合成、涂料制备及涂层性能、涂层的装饰性能特别是柔韧性能有了较大改善．

The flexible end-earboxy unsaturated polyester resins used for powder coatings and the corresponding powder coatings adopting epoxy rsein as the curing agent were preparated and researched,The synthesis of the resins,the preparation of the coatings and the properties of the coating layer were discussed.The decorationand flexibility of the coatings were improved.
