Collection: Polymerization Initiators

Polymerization Initiators — encompasses compounds that trigger polymerization reactions, generating reactive species in the form of free radicals or cations upon exposure to light (photoinitiators) or heat (thermal initiators), including acetophenone derivatives, iodonium salts, and anthraquinone compounds as its main classes.

Polymerization Initiators are used in UV ink curing, photopolymer coatings, and 3D resin printing, where iodonium-type photoinitiators or acetophenone derivatives initiate radical or cationic polymerization upon irradiation. Thermal initiators are used in thermal curing processes for composite and adhesive production, while researchers in photoresponsive materials use a combination of both to control the speed and profile of hardening.

Example products in this collection: TCI H0193 99-93-4 4'-Hydroxyacetophenone, TCI B5598 60565-88-0 Bis(4-methylphenyl)iodonium Hexafluorophosphate, TCI A0104 121-71-1 3'-Hydroxyacetophenone, TCI B5661 62051-09-6 Bis(4-tert-butylphenyl)iodonium Tetrafluoroborate, TCI A0502 84-65-1 Anthraquinone, TCI B6071 194999-85-4 Bis(4-tert-butylphenyl)iodonium Nonafluoro-1-butanesulfonate, TCI A0508 153277-35-1 Sodium Anthraquinone-2-sulfonate Monohydrate, TCI B6168 125051-32-3 Bis[2,6-difluoro-3-(1H-pyrrol-1-yl)phenyl]titanocene.

Initiator selection should consider the activation wavelength for photoinitiator classes, the decomposition temperature for thermal initiator classes, as well as storage stability and solubility in the resin system used. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
