Research and Analysis on the Advantages and Characteristics of Pure Polyester Powder Coatings in China

The powder coating made of pure polyester resin has the following characteristics: good weather resistance of the coating film, suitable for outdoor product coating; The coating has good heat resistance and is not prone to yellowing during baking and curing; The coating has excellent physical properties such as impact strength, flexibility, and hardness, as well as good resistance to chemicals and water; The coating has good coating performance and can be coated using methods such as air spraying and electrostatic powder coating; During the baking and curing process of TGIC cured polyester powder coatings, there are basically no reaction by-products, and the coating film is not prone to shrinkage, pinholes, and other defects.
The powder sprayed simultaneously can be recycled and reused; Usually easier to apply than liquid coatings, the resulting film has good durability and significant product advantages. Although epoxy resin powder coatings have more advantages, it cannot be denied that pure polyester powder coatings have equally obvious advantages. The leading product of Shenjian Corporation, polyester resin, as a new chemical material, is an important raw material for powder coatings and belongs to the powder coating sub industry of the coating industry.
