UCECOAT® 7200
Waterborne Urethane Acrylate for Hardcoat Applications
INTRODUCTION
UCECOAT 7200 is a novel(1) energy curable solvent-free urethane acrylate in
water developed for hardcoat applications. This urethane acrylate is highly
reactive upon cure and exhibits high scratch and abrasion resistance after curing.
Due to its low viscosity, it can be used as the main binder in waterborne
hardcoat formulations for spray or curtain coater. UCECOAT 7200 can be
blended with other waterborne UV resins (after pH neutralization) to increase
solids content and/or hardness property.
PERFORMANCE HIGHLIGHTS
UCECOAT 7200 is characterized by:
• Low viscosity
• White appearance
UV/EB cured coatings based on UCECOAT 7200 are characterized by the
following performance properties:
• High solids content
• Very high reactivity
• Very high hardness and scratch resistance
• Excellent stain resistance
• Direct adhesion to various plastic substrates

FORMULATION GUIDLINES
The actual properties of UV/EB cured products also depend on the selection of
other formulation components, such as additives and photoinitiators, as well as
curing conditions.
UCECOAT 7200 can be further diluted with water. Blending with other
waterborne UV resins require the pH to be adjusted to higher values by addition
of an amine, for instance triethylamine or Advantex(6).
SUGGESTED APPLICATIONS
If necessary, the coating appearance can benefit from the addition of an anticrater and wetting agent such as Tego Twin 4100(7), typically added at a
concentration of 0.5 % in the wet formulation. It is always recommended to stir
the product prior to use.
Formulated UV/EB curable products containing UCECOAT 7200 may be applied
via direct or reverse roll, offset gravure, metering rod/bar coater, slot die, knife
over roll, air knife, curtain, immersion, spray, roll to roll and spin coating
methods, as well as screen printing.
UCECOAT 7200 is recommended for use in energy cured protective hardcoats
for:
• Consumer electronics (casing & display)
• Optical film
• Metallized plastics

STORAGE AND HANDLING
Before using UCECOAT 7200, consult the Safety Data Sheet for additional
information on safety and handling procedures, and recommended personal
protective equipment.
The recommended storage temperature range for UCECOAT 7200 is ≥4°C (39°F)
to ≤40°C (104°F). Protect the product from freezing. Avoid conditions that may
expose the material to high temperatures. Protect from direct sunlight. Use
with adequate ventilation. Keep container closed. After prolonged storage
product can settle and may require agitation to re-disperse. This product is
stable under normal conditions of handling and storage.
PRECAUTIONS
Avoid contact with eyes, skin and clothing. Direct contact with this material may
cause severe eye and moderate skin irritation. Repeated or prolonged dermal
contact may cause allergic skin reactions. Wash thoroughly after handling. Use
with adequate ventilation. Keep container closed.
Please refer to the Allnex Guide to Safety and Handling of Acrylate Oligomers
and Monomers for additional information on the safe handling of acrylates.
