ebeam basics
Dose versus Penetration
11/30/2017Innovatieve Coatings Cluster 5
Dose
Dose” represents the number of electrons delivered to substrate
More dose applied to a surface will not penetrate a thicker film – it will cause higher crosslink density at the surface
Units of dose are in energy/mass1 kJ/kg = 1 kGy = 0.1 MRad
Voltage
Determines how fast the electrons are traveling at impact
Determines how far into the substrate the needed dose can be delivered
Using a higher voltage to deliver a constant dose will not increase the crosslink density – it will increase the depth at which crosslinking occurs

How ebeam works
The 3 cousins
X-Ray
Electrons hit target and in the process
X-rays are generated
1 Ultra-high vacuum
2 High voltage insulator
3 Glowing filament emits electrons
4 Electrons are accelerated in a strong electric field

What does ebeam do in the industry?Curing of inks, coatings, adhesives
11/30/2017Innovatieve Coatings Cluster 17
This energy transfer causes bonds to
break in these molecules
Electrons transfer their energy to the
monomers/ oligomers/ polymers
High energy electrons are accelerated
towards the print/coating
The result: a liquid to solid film in a
small fraction of a second
Bond formations occur between
different molecules
Reactive free radicals are generated

ebeam Vs UV
11/30/2017Innovatieve Coatings Cluster 21
UV
− Energy in the form of photons
− Wavelength determines energy: typically 200 to 415 nm
− Energy unit conversion: 350 nm photon = 3.5 eV
− Total applied energy typically 0.5 J/cm2
− Penetration depends on the optical density of the material
− Penetration is controlled by the peak irradiance (power and focus) of the UV source
− Good penetration into clear materials. Limited penetration into pigmented, filled, and opaque materials
EB
− Energy in the form of accelerated e-
− Accelerating voltage determines energy:typically 80 to 300 kV
− Typical electron energy at substrate =70,000 eV
− Total applied energy typically 20 to 40 kGy
− Penetration depends on the mass density of the material
− Penetration is controlled by acceleration voltage of the beam
− Easily penetrates into clear, pigmented, filled, and opaque materials

Curing ProcessValue of ebeam
11/30/2017Innovatieve Coatings Cluster 22
Advantages
− Premium look/feel
− Excellent adhesion
− Colorblind
− Deep penetration - cures through aluminum foil
− Ambient process – allows use of thermally sensitive materials
− Uniform drying – no post-curing
− Controlled COF to process in product filling lines
− High production speeds – wet-on-wet curing possible
− Precise – dose slaved to line speed
− Odorless
− No photoinitiator
− Ultra low extractables / migration
− Low energy consumption – no CO2 emission
Limitations
− Initial Investment & Installation Cost
− Nitrogen consumption
− UV is much more developed in terms of field of research
− UV can be easily portable. More difficult with ebeam.
− Difficult to control crosslink density. UV is a much more controlled reaction.

• The HP Indigo ElectroInk is polyethylene (PE) based
• Printed surface is therefore “soft” and susceptible to scratching and abrasion
• The ink is also heat sensitive and melts at a temperature too low to withstand heat sealing, even when laminated
