Much has been written about the potential benefits of UV curable powder coatings, but little about actual the performance of the coatings for commercial applications. This paper presents test data of UV cured powder coatings on MDF.
To date the efforts to promote UV powder coatings have been spent educating those responsible for finishing about the mechanics and technical benefits of UV powder coatings compared to alternatives such as thermal cure powder, liquid paints and a wide range of laminates.

For several years DuPont Powder Coatings has been producing and selling UV curable powder coatings for commercial use on MDF furniture and PVC flooring, and in doing so offering unique advantages to our customers.
The increased pressure to reduce VOC levels in surface coatings and the constant improvements required in coating properties continues to drive the growth of UV technology. The dispersion and stabilisation of pigments in such systems can be problematical.
Powder coating cured by ultraviolet light (UV powders) is a technology that combines the advantages of thermosetting powder coatings with those of liquid ultraviolet cure coating technology.The difference from standard powder coatings is that melting and curing are separated into two distinct pro
We have now entered the third millennium and one of the most widely discussed and pressing topics of the moment, for which an immediate response has to be found, is the need to reduce environmental pollution.

Powder coatings are very attractive, environmentally friendly alternatives to liquid finishes since they are VOC-free. Resins that cure under UV light have already been developed for applications in powder coatings.

UV-curable inks and varnishes have been one of the fastest growing technologies in the past two decades. This growth is forecast to continue well into the future with the development of new applications for UV curing, such as inks for food packaging.
