ADDITOL® TPO

ADDITOL® TPO by allnex is a radical photoinitiator that can be used alone or in combination with other photoinitiators. It is used in formulations containing unsaturated materials such as acrylates, methacrylates, vinyls and polyesters. With exposure to UV light, ADDITOL® TPO undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerization through the unsaturated groups present in the system. It is suited for the UV curing of white pigmented formulations and thick clear coatings. Recommended for screen inks and white flexographic- & offset inks. It is typically used at levels of 0.5-2% by weight based on the reactive components of the formulation.
