UV curing and printing

Speed and process reliability are fundamental factors in industry. UV technologies help make the production process more reliable, more energy efficient and thus more cost-effective.

UV radiation cures UV paints, varnishes and adhesives within seconds. In contrast to conventional coatings, UV recipes are almost entirely free from solvents.

The innovative UV technology is applied in the printing industry (web-fed, sheet-fed, screen and inkjet printing), for the production of optical disks and the finishing of wood and matt varnishes, in sewer rehabilitation, medical technology, microelectronics and many other industrial processes. UV solutions are also used to expose printed circuit boards.

Advantages of UV curing:

Solvent-free technology without development of gas
Curing within seconds
High processing speeds
Resistance to solvents
Small design sizes of the installations
Energy efficient

UV curing applications:

Heraeus Noblelight also supplies excimer systems for special UV curing applications.

Curing of printing inks: Printing ink needs to be completely dried or cured before print sheets are stacked, cut, folded or glued.
The emission spectrum of the UV radiation is very important to the printing ink curing process. A sufficient number of photons need to react to ensure that the entire material is cured.
Curing of adhesives/sealing compounds: UV adhesives do not contain solvents and are therefore especially eco-friendly. Curing takes place very quickly, mostly within seconds. The components to be glued can be moved, aligned and positioned after the adhesive has been applied.
Compared to conventional methods, the glued connection has improved material properties, provided that the adhesive is adjusted to the application.
Exposure of printed circuit boards: Exposure of printed circuit boards with UV technology
Surface finishing: Surface finishing: Improvement and protection of surfaces with ultraviolet lamps
