1. Photoacid Generators (PAGs) for Cationic Photopolymerization Systems:

As a core component of cationic photoinitiators, it generates strong acids under UV irradiation, initiating the polymerization of epoxy and vinyl ether systems. It is used in UV-curing coatings, inks, adhesives, and microelectronic photoresists.

2. Strong Acid Catalyst in Organic Synthesis:

Utilizing its superacidity and chemical stability, it catalyzes esterification, etherification, rearrangement, and cyclization reactions, especially suitable for fluorochemical and fine chemical synthesis processes requiring high catalyst stability.

3. Fluorinated Surfactants and Additives:

Used in the preparation of fluorinated surfactants, improving wetting, leveling, and anti-fouling properties in coatings, inks, and polymer processing; it can also be used as a polymer modification additive to enhance the chemical resistance and surface properties of materials.

4. Electrochemistry and Ionic Liquids:

It can be used as an electrolyte additive or ionic liquid precursor in electrochemical devices such as lithium-ion batteries and supercapacitors, improving ionic conductivity and stability; it is also used in the preparation of proton exchange membrane materials, suitable for fuel cells and other applications.

5. Fluorochemical Intermediate:

Used in the synthesis of fluorinated fine chemicals, such as perfluorobutylsulfonyl fluoride and fluorinated pharmaceutical and pesticide intermediates, it is a key raw material in the fluorochemical industry chain.

6. Material Surface Modification and Treatment:

Used for surface treatment of substrates such as metals, glass, and polymers, forming a dense fluorosulfonic acid layer to impart corrosion resistance, stain resistance, and superhydrophobic properties to the substrate. It is suitable for precision instruments, electronic components, and chemical equipment.
