ADDITOL® CPK

Technical Datasheet | Supplied by allnex
ADDITOL® CPK 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 unsaturated polyesters. With exposure to UV light, ADDITOL® CPK undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerization through the unsaturated groups present in the system. It exhibits good solubility. This grade is characterized by good surface, through cure and low yellowing on cure with exterior exposure in UV curable formulated products. Applications include paper upgrading, wood top-coats, hard-coats for plastics, overprint varnishes, vinyl flooring, metal & pigmented coatings and inks. The recommended usage level is 1-5% by weight based on the reactive components.
