DAROCUR®1173

General

DAROCUR®1173is a versatile highly efficient liquid photoinitiator which is used to initiate the photopolymerisation of chemically unsaturated prepolymers - e.g. acrylates - in combination with mono- or multifunctional monomers.

Chemical Composition

Absorption Spectrum


(% in Acetonitrile)

Physical Properties Appearance: colorless to slightly yellow liquid
Odor: slight
Miscibility: in most common organic solvents as well as most
acrylate based monomers exceeds 50g/100g;
practically insoluble in water.
Melting point: 4°C
Boiling point (at 0.13 mbar ~ 0.1 Torr): 80 - 81°C
Flashpoint: > 100°C
Density : 1.08 g/cm3

Viscosity (at 20°C): 25 mPa.s
Application

DAROCUR®1173may be used after adequate testing for applications such as UV curable clear coatings based on acrylates for paper, metal and plastic materials.
As a liquid UV curing agent with excellent compatibility, DAROCUR®1173 is especially easy to incorporate. It is therefore highly suitable for blends with other photoinitiators.
DAROCUR®1173 is especially recommended when UV coatings are required to exhibit only minimal yellowing even after prolonged exposure to sunlight. Yellowing of urethane acrylates may be further reduced by addition of Ciba Specialty Chemicals hindered amine light stabilizer TINUVIN ® 292.The amount of DAROCUR®1173required for optimum performance should be determined in trials covering a concentration range.

Recommended concentrations :

film thickness: 5 – 20 mm 2.0 – 4.0 %DAROCUR®1173

film thickness: 20 – 2000 mm 1.0 – 3.0 %DAROCUR®1173

Safety and Handling

DAROCUR®1173should be handled in accordance with good industrial
practice. Detailed information is provided in the Safety Data Sheet.
