Technological breakthrough in cationic photoinitiators with Irgacure® 270


* Fast UV curing, low emission, low odor
* Successful use in food packaging

With Irgacure® 270, BASF made a technological breakthrough in the development of cationic photoinitiators for packaging inks. For the first time, Irgacure® 270 now makes it possible to combine fast UV curing with very low emissions. This new product is very versatile, and its applications include both UV-curable printing inks and clear overprint varnishes.

Photoinitiators are substances that form free radicals when they are exposed to UV light, and these radicals initiate polymerization reactions. Irgacure® 270 is a new high-molecular-weight sulfonium salt which fulfills the high standards that UV-curable inks for food packaging are required to meet. Extensive tests have shown that emissions and migration are both very low. A complete registration package has been put together.

Irgacure® 270 is mainly employed in UV-curable applications that demand low-emissions. These include clear overprint varnishes, flexographic inks, screen inks and inkjet inks for printing food packaging made from a variety of substrates such as paperboard, plastics and metal.
