SINOCURE® 6992

Mixed triarylsulfonium hexafluorophosphate salts, cationic photoinitiator, UV flexo inks

Sinocure® 6992 is a mixed triphenyl sulfonium hexafluorophosphate soluble in propylene carbonate. It is a light yellow
transparent liquid. Sinocure® 6992 can be used for cationic curing of inks, epoxy resin coatings, oxetane and vinyl ether
formulations. And Sinocure® 6992 has fast curing speed, low odor and excellent post curing.Sinocure® 6992 photoinitiator is used to UV-cure cycloaliphatic epoxide resins such as Sinepoxy® CER-421 and Sinepoxy® CER-4299, vinyl ethers and other cationically curing materials.
