Preparation, handling and spraying procedures for a UV-curable powder formulation are similar to those for a thermosetting powder formulation. But in UV-curable powder coatings, melting/flow-out and curing are two separate processes. Upon exposure to heat, UV-curable powder coatings melt and flow into a smooth film. Cross-linking occurs when the molten film is exposed to UV light.
