Description

General description

Mixed triarylsulfonium hexafluorophosphate salts are cationic photoinitiators which are used as ultraviolet curing agents that have bifunctional cross-linking monomers.

Application

It can be mixed with propylene glycol monomethyl ether acetate (PGMA) that may be blended with bisphenol F resin which can be used in the fabrication of UV curable nano-imprinted epoxy resist. It can also be used as a photo-initiator for photo-polymerization of epoxy/acrylate composites which find applications in UV protective coating on electronic devices.
