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. | |

Recubrimientos en polvo de curado UV sobre plásticos y compuestos
| Application Data | ||
|---|---|---|
| Application | Powder is typically sprayed using corona electrostatic spray guns. Most plastic materials and some carbon fiber materials require use of a conductive aid to allow for electrostatic transfer. Contact Keyland Polymer for more information. | |
| Melt | Melt times will range from 0.5-3 minutes depending on polymer base, part size/ dimensions, oven set temperatures, and type of oven. | |
| UV Cure | It is recommended that UV powder coatings be cured using gallium-doped lamps with a UVV dosage of 2000-4000 mJ/cm2 and UVV intensity of 1000-2000 mW/cm2. A coating temperature of 105-140°C (221-284ᵒF) 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 (65ᵒF) for 6 months are recommended for storage stability. Contact Keyland Polymer to confirm the appropriate storage conditions for your product. | |

Pintura en polvo de curado UV sobre madera
| Application Data | ||
|---|---|---|
| Application | Powder is typically sprayed using corona electrostatic spray guns. Preheating of MDF should be kept to a minimum to reach recommended surface temperature of 60-70°C (140-158°F), typically 1-2 minutes. | |
| Melt | Melt times will range from 1-3 minutes depending on MDF thickness, part size, oven set temperatures and type of oven. | |
| UV Cure | It is recommended that opaque 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 100-130°C (212-266°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. | |
