Instant conversion of a reactive liquid in a solid induced by ultraviolet

radiation through double bonds

Market Environment:

Growing segment due to versatility

Variety of compositions

Cost / Competitiveness – Quality

Technical Challenges - ADHESION:

Crystallinity

Polarity

Surface Tension

Shrinkage

ALL of these vs. Mechanical and Chemical Performance (Toughness/Flexibility, Scratch and chemical resistance, yellowing, monocoats)

> crystallinity, the more difficult it is to get adhesion

When the liquid meets the solid – Contact Angle

CHALLENGES for UV curing:

POLARITY of regularly used components, which leads to higher

surface tensions

SHRINKAGE of the cured film due to retraction during the

conversion of monomers and oligomers into a polymer

ROUTE PRODUCT Effect

Lowering the Tg of the ink

EBECRYL® 767 (acid modified)

EBECRYL® 8411 (300% elong.)

EBECRYL® 242

Less double bounds in the system

will lead to a lower shrinkage of the

film, helping on the adhesion.

Improve interaction between

the film phase and the

substrate

EBECRYL® 438

EBECRYL® 524 (acid modified)

chlorination plays an important

adhesion promoting role.

Surface tension balance EBECRYL® 303

Better substrate wetting enabling

good adhesion and leveling

Addition of acidic modified

methacrylate adhesion

promoters

Substrate anchoring promotion

Substrate pre-treatments, such as corona or flame treatment. Even the use of primers.

EBECRYL® 571 Shrinking Properties

EBECRYL® 571 Shrinking Properties

Ink film thickness: 1 ~ 2µµµµm

EBECRYL 452 is a new energy curable resin, that combines low viscosity

along with excellent pigment wetting properties.

• Functionality, theoretical 4

• Dynamic viscosity ~600 cP at 25°C

• Density 1.15 g/cm3

• Appearance Clear, dark amber liquid

• Suitable for use with 3 roll mills where higher pigment loadings is achieved versus using

standard grind vehicles.

• Allows low viscosity pigment concentrates to be produced, for use in bead mills.

• Can be used for a wide range of organic and inorganic pigments.

• Minimizes the use of low molecular weight and low functionality products.
