1. UV Cationic Curing Coatings:

Used in UV-curing coatings for epoxy resins, vinyl ethers, and other systems, providing high-gloss, wear-resistant coatings for metal, glass, and plastic substrates. Especially suitable for thick films (>10μm) and high-pigment content systems, improving coating hardness, chemical resistance, and adhesion. Compatible with LED/mercury lamp UV curing systems.

2. Electronic Materials and Photolithography:

Used in microelectronic photoresists (such as SU-8 type epoxy photoresists), PCB solder masks, and encapsulation materials. Acts as a photoacid generator to initiate cationic polymerization, enabling fine pattern transfer, improving circuit insulation and moisture/heat resistance. Suitable for semiconductor and high-density PCB manufacturing.

3. Printing and Packaging Inks:

Used in lithographic printing plates and flexographic/screen printing UV inks, especially suitable for high-pigment inks and thick-film printing. Used in conjunction with photosensitizers (such as isopropyl thioxanthone) to improve curing efficiency and print weather resistance. Suitable for food-contact packaging printing.

4. Hybrid Photocuring Systems:

Used in free radical/cationic hybrid photocuring systems, suitable for photocuring adhesives, sealants, and composite materials. Combines the fast surface curing of free radical curing with the deep curing of cationic curing, improving overall product performance.

5. Optical Materials and Fiber Optic Coatings:

Used in UV-curing coatings for optical components and fiber optic coating materials, enhancing light transmission and aging resistance. Suitable for the manufacture of high-precision optical components and communication fibers, improving product optical performance and stability.

6. 3D Printing and Photosensitive Resins:

Used as a cationic photoinitiator in SLA/DLP photosensitive resins, suitable for 3D printing of epoxy resin-based photosensitive materials, enabling high-precision molding of complex structures. Applicable to the rapid manufacturing of industrial parts, dental models, etc.

7. Organic Synthesis and Catalysis:

Used as a photosensitive reagent and catalyst in photo-induced organic synthesis, carbon-carbon bond coupling reactions, and arylation reactions, suitable for laboratory organic synthesis and the preparation of fine chemical intermediates, improving reaction selectivity and efficiency.

8. Polymer Material Modification:

Used in the synthesis and modification of photosensitive polymers (such as polyurethane acrylates and epoxy acrylates), imparting photoresponsive properties to materials, suitable for the preparation of smart materials and functional films, and controlling the degree of crosslinking and performance of the materials.
