Powder coatings have advantages such as no organic solvents, environmental friendliness (compared to oil-based coatings), high material utilization, low energy consumption, and are easy to apply with low cost. They have good corrosion and weather resistance and are suitable for products and facilities with low requirements for corrosion and weather resistance. They have been widely used in many fields of manufacturing. Among them, polyester powder coatings are widely used in outdoor facilities such as buildings, automobiles, and transportation due to their excellent comprehensive performance and relatively low cost advantages. Currently, more than half of thermosetting powder coatings are prepared using polyester resin as the base material.
