Speedcure 938 Property
Sinocure ®938 is cationic photoinitiator of the iodonium hexafluorophosphate family, designed for non-silicone applications such as the cationic UV curing of inks to speed up the rate of curing. This crystalline powder enables good adhesion to metal substrates and presents low yellowing in clear coatings and thin films in addition to its use to cure cycloaliphatic epoxy resins, vinyl ethers, glycidyl ethers, oxetane, epoxidised olefins and other cationically cured materials.
Its absorption maximum is 241nm. Sinocure ® 938 provides high reactivity and solubility in cationic systems when used at 0.5-5 wt% in UV curable formulations and LED curable formulations when sensitised with thioxanthones
