Technical Datasheet | Supplied by allnex
ADDITOL® EPD by allnex is an amine co-initiator for radical UV curing. In combination with a hydrogen abstraction photoinitiator such as ADDITOL® ITX, ADDITOL® EPD is used in formulations containing unsaturated materials such as acrylates, methacrylates, vinyls and unsaturated polyesters. With exposure to UV light, it undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerization through the unsaturated groups present in the system. It exhibits light odor, good solubility, good surface and depth of cure with pigments. It is suitable for pigmented coatings, and screen-, offset- & flexographic inks. This grade is typically used at levels of 2-6% by weight, in combination with 1-3% ADDITOL® ITX based on the reactive components of the formulation.
