Advantages: Simple processing and coating methods require only heating, melting, leveling, cooling, or extraction to solidify the film. No complex curing equipment is required, making it easy to achieve thicker coatings (up to 250μm thick) and offering a better performance-to-performance ratio.
Disadvantages: Difficult to crush to fine particles, and due to the requirement for a high molecular weight binder, the coating exhibits poor leveling at baking temperatures.
Thermosetting Powder Coatings
Advantages: The resulting film’s appearance, various mechanical properties, and corrosion resistance surpass those of oil-based paints. Raw material utilization is high, and oversprayed powder can be recycled, with the highest recycling rate exceeding 99%.
Disadvantages: Uneven application of powder to edges and corners, difficulty concealing film defects after curing, demanding curing conditions, and limited substrate compatibility.
