Omnirad 403

Technical Datasheet | Supplied by IGM Resins

Omnirad 403 by IGM Resins is a versatile photoinitiator for radical polymerization of unsaturated resins upon UV light exposure. It exhibits of high reactivity and can be used in high end optical applications.

It offers outstanding absorption properties which allow the curing of thick layer.
It is used for thick layers and particularly in clear applications.
It is recommended for clear and for pigmented coatings on wood, metal, plastic, paper as well as for printing inks.
It can be used in combination with other photoinitiators such as Omnirad 184.
Omnirad 403 is suitable to cure polyester/styrene resins used for glass-fiber reinforced materials.
Due to its photo sensitivity at longer wavelengths, Omnirad 403 can easily be used in combinations with UV absorbers.
It is also used in weather-resistant UV curable coatings.
