Recubrimientos en polvo de curado UV sobre metal

Application Data
Application Powder is typically sprayed using corona electrostatic spray guns.
Melt Melt times will range from 1-4 minutes depending on metal thickness, part size, oven set temperatures and type of oven.
UV Cure It is recommended that UV powder coatings be cured using gallium-doped lamps with a UV-V dosage of 2000-4000 mJ/cm2 and UV-V intensity of 1000-2000 mW/cm2. A coating temperature of 110-140°C (230-284°F) is recommended at the time of cure.
UV LED Cure Unpigmented and pigmented powder coatings will cure using a UV LED lamp under the correct parameters. Contact Keyland Polymer for product and process information.
Storage and Shelf Life Dry and cool conditions below 18°C (65°F) for 6 months are recommended for storage stability. Contact Keyland Polymer to confirm the appropriate storage conditions for your product.
