ADDITOL® DMMTA is a radical photo-initiator 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.
