Abstract

The effects of trimethylolpropane,diethylene glycol,and ethylene glycol on the matting properties of polyester resin were studied,and a 60/40 polyester resin suitable for polyester/epoxy system matting powder coatings was prepared.At the same time,the application of this polyester in matting powder coatings was studied for its adaptability to matting agents and baking furnace temperature.The experimental results show that the 60/40 matte polyester synthesized in this article has good compatibility with different types of matte agents,and the fluctuation of baking furnace temperature has little impact on the performance of the powder coating.The matting powder coating prepared using this polyester also has good mechanical properties and a smooth and delicate appearance.
