Specialty Photoinitiators

PowerCure™ 784 is a highly reactive orange solid photoinitiator for free radical polymerization of unsaturated resins under visible light (sunlight) or ultraviolet light, and the best performance can be obtained in the absence of oxygen.

PowerCure™ 784 is a fluorinated diaryl biscyclopentadienyl titanium complex. No primary radicals are formed, and titanocenes are neither type I nor type II molecules. The excited state of the titanocene forms a complex with the acrylate monomer to produce a monomer radical that initiates polymerization.

Its unique light-absorbing properties and its excellent reactivity make it particularly suitable for use in photopolymers such as resists, printing plates and other information storage devices such as optical layers, holograms, laser direct imaging, stereolithography. PowerCure™ 784 has photobleaching properties and can be used in clear and pigmented systems.

TINTOLL is one of the leading photoinitiator manufacturers, which is also one of the cornerstone businesses of TINTOLL. Our product portfolio covers free radical and cationic photoinitiators (photo-acid generators) as well as amine synergists. UV-curable materials are widely used in graphic arts, industrial coatings, adhesives, printed circuit boards, and 3D printing. TINTOLL provides application support, product development and custom solutions, and collaborates with customers to develop next-generation photoinitiators.
