Technical Datasheet | Supplied by allnex
ADDITOL® DMMTA by allnex is a radical photoinitiator that can be used alone or in combination with other photo-initiators. It is used with unsaturated materials such as acrylates, methacrylates, vinyls and unsaturated polyesters. When exposed to UV light, a photochemical reaction occurs generating radicals which will initiate polymerization through the unsaturated groups present in the system. It exhibits good solubility and low volatility. This grade is characterized by good surface and through cure in UV curable formulated products. ADDITOL® DMMTA is suitable for the curing of pigmented coatings and inks. Suggested applications include flexographic-, offset- and screen inks. The recommended usage level is 2-4% by weight based on the reactive components of the formulation.
