Spectra Group Limited H-Nu 470 initiates both free-radical and cationic photopolymerization, using a different set of co-initiators depending on the polymerization process
• Type II photoinitiator: H-Nu 470 acts as a light harvester, followed by energy or electron transfer to a co-initiator molecule; produced
reactive species activate photopolymerization
• Commercial photoinitiator (TSCA status: LVE), non-toxic (LD50>5000 mg/kg).
