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.
