1. Cationic UV Curing Coatings:

Used in epoxy, vinyl ether, and other systems, providing high-gloss, wear-resistant coatings for substrates such as metal, glass, and plastics. Particularly suitable for thick film (>10μm) systems using titanium dioxide as a pigment, improving coating hardness, chemical resistance, and adhesion. Compatible with LED/mercury lamp UV curing, suitable for coatings on building materials, home appliance casings, and metal pipes.

2. Food Contact Packaging and Printing:

Used in UV offset, flexographic, and screen printing inks, suitable for indirect food contact packaging printing, complying with relevant FDA safety standards. Improves print gloss and scratch resistance, suitable for labels, cartons, and flexible packaging.

3. UV Adhesives and Sealants:

Used in cationic UV adhesives and sealants, suitable for bonding electronic components, optical components, glass, and metal. Improves bonding strength and aging resistance, and can also be used in indirect food contact packaging adhesives and sealing applications.

4. Electronic Materials and Photolithography:

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

5. Hybrid Photocuring Systems:

Used in free radical/cationic hybrid photocuring systems, suitable for photocuring adhesives, sealants, and composite materials. Combines the rapid surface curing of free radical curing with the deep curing of cationic curing, improving overall product performance. Suitable for complex formulations and thick film applications.

6. Optical Materials and 3D Printing:

Used in UV-cured coatings for optical components and fiber optic coating materials, enhancing light transmission and aging resistance; also used as a cationic photoinitiator in epoxy resin-based SLA/DLP photosensitive resins, enabling high-precision molding of complex structures. Suitable for 3D printing of precision parts, optical components, and dental models.

7. Other low-odor, environmentally friendly UV curing applications:

Used in leather finishing, paper varnishing, etc., meeting low-odor and environmentally friendly requirements, improving product surface performance and lifespan. Suitable for processing high-end leather products, fine printed materials, and other applications, especially those sensitive to odors.
