Powder Coating Plastic
There are many different types of plastics that can be successfully coated with UV-curable powder coatings. Each type of plastic has different properties, meaning some will coat better than others. Please contact us to determine if your plastic can be coated.
UV-cured powder coating works on plastic because the time to melt the powder is short and the temperatures used are low. Most plastics are non-conductive in nature and may require a primer to make them suitable for electrostatic powder coating.
Our chemists will work with you to formulate a functional coating for your plastic material. The more information initially provided about the properties of the plastic the better.
Fill out our Finish Requirements Form if you have an existing project you feel UV powder could be a fit for.
UV-Cured Powder Coating on ABS
|UV Cure||It is recommended that opaque powder coatings be cured using gallium-doped lamps with a UV-V dosage of 1500-3000 mJ/cm2 and UV-V irradiance of 1000-2000 mW/cm2.|
|Storage and Shelf Life||Dry and cool conditions below 65°F for 6 months (formulation can affect storage stability – contact Keyland Polymer to confirm the appropriate storage conditions for your product)|
