Description

Triarylsulfonium Hexafluorophosphate Sal Ts, Mixed, 50% In Propylene Carbonate is a high-purity, mixed triarylsulfonium salt photoacid generator (PAG) formulated as a stable solution. This compound is a critical component for initiating cationic polymerization upon exposure to ultraviolet (UV) or deep ultraviolet (DUV) light sources. It is essential for advanced manufacturing in the electronics and specialty coatings industries, where precise and efficient photochemical curing is required.

Application

• Photoresists for Semiconductor Manufacturing: A key photoacid generator (PAG) in chemically amplified resists (CAR) for deep-UV (248nm) and extreme-UV (EUV) lithography processes.
• UV-Curable Coatings and Inks: Initiator for cationic polymerization in coatings, inks, and adhesives that cure under UV light, offering excellent adhesion and chemical resistance.
• Optical Fiber Coatings: Used in the production of protective, fast-curing coatings for optical fibers.
• Printing Plates and Stereolithography: Facilitates rapid curing in the production of printing plates and for 3D printing via stereolithography (SLA).
• Electronic Encapsulants and Potting Compounds: Enables the UV-initiated curing of protective compounds for electronic components.
• Advanced Composite Materials: Acts as a curing agent in the production of fiber-reinforced polymer composites using light-assisted techniques.
