How you can benefit
from Radiation Curing
Radiation Curing is a fast growth technology that is rapidly
developing and expanding into new application areas, which
include glossy magazines, wood coating, and electronic
What makes the technology even more compelling is the
exceptional performance in terms of high printing line
speed and print quality.
Taking on the toughest
challenges
Cationic UV Curing takes on the toughest challenges, such
as printing or coating on tricky substrates or where low
migration and exceptionally high quality are demanded.
UV light initiates the cationic reaction, but curing continues
until through cured even in darkness. This ensures a robust
quality print finish that lasts irrespective of whether it is
metal, plastic, or glass food packaging substrates or even
automotive coatings.
Inherent to the technology is also low shrinkage and exceptional flexibility making it ideal for demanding applications
such as shrink sleeves. In addition to Curalite™ Ox and
Curalite™ OxPlus, Perstorp offers a broad range of components for Cationic UV Curing.

Faster reactivity & lower
formulation costs
Curalite™ is our range of Oxetane diluents that bring powerful performance and impressive speed to your Cationic UV
Curing formulations. Adding Curalite™ Ox dramatically
increases the reactivity of your formulation, which in turn
boosts the speed of printing or coating line. You can even
decrease your formulation costs and increase your competitiveness, as you require less photoinitiator with Curalite™.
If you still need extra performance try our Curalite™ OxPlus,
which will cure your need for speed as you get up to 15x
faster reactivity in formulations. On top of that, you gain
from increased through cure and hardness.
Curalite™ gives your formulations
that extra edge
Curalite™ Ox
Cationic UV Curing, as a technology, is already a great
solution to meet the increasing demands for faster, and
more efficient production. Add Curalite™ Ox, and you can
take cationic to the next performance level. Using between
5 and 20% of Curalite™ Ox in your formulation can boost
the reactivity by up to a factor of 7.
Cationic formulations are normally made up of 3 main
components:
ÆÆ Cycloaliphatic epoxides (e.g. 3,4 epoxy cyclohexyl
methyl-3,4 epoxy cyclohexane carboxylate)
ÆÆ Photoinitiator
ÆÆ Diluents

Curing your need
for speed
By using Curalite™ Ox, as your diluent, you not only get
the required decrease in viscosity, but you also gain:
Reactivity
ÆÆ Higher
line speed
ÆÆ Compensates for cationic sensitivity to moisture in the air
Increased end product quality
ÆÆ Gives the best combination of flexibility, hardness and
chemical resistance
Curalite™ Ox increases the dark cure, which greatly improves
the through cure of cationic formulations. This ensures you
get a consistent and high-quality printing result across all
the core substrates.
Curalite™ Ox speeds up the reactivity, so you need less photoinitiator, which is an expensive part of your formulation.
This resource efficiency enables you to lower the total cost
of your formulation making you more competitive.
Curalite™ Ox offers outstanding performance in handling
and safety. It is clear, colorless, with very low odor and no
skin-irritation.
The unique properties of Curalite™ Ox make it the given choice
in formulations for applications with high demands like:
ÆÆ Food packaging where safety, low migration, low odor
and scratch resistance are key
ÆÆ Shrink sleeves where the focus is on superb flexibility
ÆÆ Coatings for beverage can-bases for long-term resistance,
fast processing and customized slip and resistance.
Curalite™ OxPlus – Up to 15x faster reactivity
For the applications where only the best performance will
do Curalite™ OxPlus is the perfect solution. Offering up
to 15x faster reactivity it “cures the need for speed” and
the complete through cure ensures outstanding toughness
and a superb finish every time. General recommendation
is to use between 10 and 40% Curalite™ OxPlus in your
formulation.
Curalite™ OxPlus is one of the very few solutions that can
be used to speed up the printing line in humid and high
moisture content environments. You can also use Curalite™
OxPlus in combination with Curalite™ Ox to fine-tune
your formulations so that they match your customers’ specific
demands. For example a formulation of 20% Curalite™ Ox
and 15% Curalite™ OxPlus gives excellent flexibility and
through cure.
