ebeam basics

Dose versus Penetration


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

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


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

ADDITIVES: provide special functional properties.

MONOMER: reactive diluents, influences crosslink density.

OLIGOMER: provides the basic polymer properties.

NO PHOTOINITIATOR PHOTOINITIATOR: generates primary free radicals if exposed to UV light.

ebeam Vs UV


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


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

HP Indigo is the leading digital printing method. Why? The combination of high-quality

graphics and digital flexibility
