Molecular Structure


Syna PI 907 is a radical photo initiator that can be used alone or in combination with other photo initiators. It is used in formulations containing unsaturated materials such as acrylates, methacrylates, vinyl’s and unsaturated polyesters. With exposure to UV light, Syna-PI 907 undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerization through the unsaturated groups present in the system.
Syna PI 907 is particularly suited for the curing of pigmented coatings and inks. The reactivity of Syna PI 907 can be significantly improved when combined with Syna PI ITX.


Syna-PI 907 is typically used at levels of 2-4% by weight based on the reactive components of the formulation. The addition of 0.2-0.4% Syna-PI ITX can  significantly improve reactivity. Applications include:
•  Flexographic inks
•  Offset inks
•  Screen inks
•  Pigmented coatings
