Omnirad 369 / IRGACURE 369 Usage

1. Sinocure® 369 is a highly efficient UV photoinitiator with a high sensitivity range and high UV absorption, used to initiate free radical photopolymerization reactions and can be used in UV-curable inks and coatings in combination with appropriate co-initiators such as 184 or 651, 907, ITX

2. Sinocure® 369 is particularly suitable for UV curing of colored systems, especially blue and black color systems, and can even be used in systems containing UV absorbers such as.

3. Sinocure® 369 is used in packaging applications, such as offset printing, screen inks, etc., in the electronics industry, such as: photoresist, solder resist inks, etc., and in the manufacture of printing plates.

4. Due to Sinocure® 369 photoinitiator’s initiation effect depends largely on different formulations, the best effect and addition amount should be obtained by formulation tests.

Recommended addition amounts.
Offset inks 2 – 4%
Screen ink 2 – 4%
Color varnish 1.0-4%

5. Sinocure® 369 allows the preparation of a low-energy UV-curable card making offset ink.

Including the following mass percentage components: two functionalities modified polyester acrylate 40-50%; dipentaerythritol penta/hexa acrylate 5-10%; ethylene oxide trimethylolpropane trimethacrylate 5-10%; 1,6-hexanediol diacrylate 1-3%; photoinitiator combination 10-16%; pigment 15-20%; filler 3-5%; additives 1-3%. The photoinitiator combination includes the following mass percentage components: 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)butanone (photoinitiator 369) 15-20%; phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide 15-20%; 2,4,6-trimethylbenzoyl-diphenylphosphine oxide 15-20%; 2-dimethylamino-2-benzyl-1-[- 4(4-morpholinyl)phenyl]-1-butanone 20-25%; 2,4-diethylthioanthrone 20-25%. The present invention also discloses the preparation method and application of the ink.
