UV, EB and UV LED are complementary - not competing technologies. The technologies have some similarities and at the same time some fundamental differences. Please read through our Technology Centre to learn more.
The selection of technology should be based on the best fit for the process and application. Some of the considerations may include; enabling of end-use, process integration, capital cost, operating costs, end-use properties and substrate considerations.
If you are unable to find the needed information on our web site, our experts are always available for a discussion to find the optimum solution to match your needs.
Comparisson for UV & EB
Both UV and EB are more efficient than thermal curing resulting in less energy consumption.
Substrates are not exposed to high temperature when curing with UV and EB.
Both UV and EB instantaneously converts low-viscosity liquids to durable polymer inks or coatings.
Differences between UV & EB
UV curing is conducted in air where EB curing is conducted in nitrogen resulting in minimal oxygen inhibition in EB cure.
The thickness of pigmented ink or coating is limited when curing with UV as the pigments absorbs the UV light energy. The opacity of the ink or coating is however irrelevant using EB curing.
There is a risk of cured ink or coating yellowing upon exposure to sunlight after being cured with UV. This is not an issue curing with EB as photo initiators are not used in the EB process.
EB curing units are in general considerable more expensive than the UV curing unit.
