ADDITOL® CPK 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.
Suggested applications for ADDITOL® CPK include: paper upgrading, wood top-coats, hard-coats for plastics, overprint varnishes, vinyl flooring, metal coatings, exterior applications, general coating applications where low yellowing is critical, and inks and pigmented coatings (in combination with other photoinitiators).
