UV Curing



What is UV curing?

UV curing is based on changing the state of the matter, else said a product applied as a liquid or a paste is to be solid after UV irradiance.
Therefore, several coatings chemistries are available on the market, requiring various UV wavelengths, either over a spectrum encompassing UV-A to UV-C, we are then talking about “UV lamp”, or a specific UV wavelength, we are then talking about an LED source (UV-A)

Why UV curing?

The UV Polymerization after conformal coating or dispensing allows shorter cycle times compared to IR Drying classical solutions and then requires minimized foot print. The environmental impact is reduced due to the non use of solvent based varnishes. Consequently the polymerization line doesn ‘t need solvent treatment and finally the energical impact is reduced too.

Maximize wettability and adhesion, and ease quality control on your coating lines

In order to leverage the quality and ROI of your coating lines, EXELSIUS recently developed two innovative products:
– Genius®, a 3D self-programmable and robust solution for selective surface activation by atmospheric pressure plasma,
– XVIEW, when AOI is not required, and direct operator visual control is not sufficient…


EXELSIUS’ XUV and XUV LED curing ovens stand as the world reference for UV curing applications, with numerous systems installed for global leaders as well as high-end small size customers, especially in highly demanding applications in the Aerospace & defence, Automotive, Industrial and Medical sectors.
