Treatment with intensive UV light can prepare surfaces for better flow and adhesion of coatings, inks and adhesives.
Do you need to remove organic contamination from glass surfaces?
Do you want to activate the surfaces of plastics?
UV technology can do this. See how it works!
How does UV activation and cleaning of surfaces work?
High-energy UV photons are able to break up molecular organic bonds at and on surfaces.
This UV oxidation process cleans the surface of contaminants.
It also leads to the introduction of functional groups such as hydroxyl, carbonyl or carboxyl groups which increases the surface energy of a surface which improves both wettability and adhesion.

To pretreat surfaces with UV, use specialty light sources which can generate high radiation in the low-wave spectral range below 200 nm.
