Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a thermosetting powder coating. Background technique [0002] Powder coating is a new type of coating that does not contain solvents and forms a coating film after construction and coating in powder form. Compared with traditional solvent-based coatings, powder coatings emit almost zero organic solvent volatiles (VOC) during curing, avoiding environmental pollution; at the same time, powder coatings have high utilization rate, good coating performance and easy implementation Advantages such as automated coating have achieved rapid development in recent years. [0003] At present, there are many kinds of thermosetting powder coatings, mainly including epoxy resin powder coatings, epoxy / polyester powder coatings, polyester powder coatings, polyurethane powder coatings and polyacrylate powder coatings. With the development of society, the performance of existing thermosett...
