What is UV / EB radiation curing?

Radiation curing is a process where the energy of UV-light or electron beams is used to induce a radical reaction and thereby facilitate polymerization in a coating or in an adhesive. Specific short-wave radiation types are used for this process:

EB (electron beam)	Curing by accelerated electrons in the engery range of 90 to about 250 KeV (Kilo-elektron-volt)
UV (Ultra-violet)	Curing by UV-light in the specific wave length of 240 to about 420 nm

This process only needs fractions of a second so that pieces with radiation-cured coatings or adhesives can be handled immediately after the coating/adhesive was applied and subjected to radiation. A clear advantage when it comes to productivity. It explains the increasing popularity and growth of this technology.

Radiation sources are generally special UV-lamps or an electron beam system equiped with an electron gun plus sometimes a particle accelerator. Bayer MaterialScience cooperates with the makers of this equipment in order to achieve an optimum performance of the coating / adhesive system with the equipment setup.
