Product Description:
Photoinitiator 2074 is a high-performance diaryliodonium salt widely used in UV-curable and LED-curable systems. It generates strong Brønsted acid upon irradiation, enabling rapid cationic polymerization of epoxides, vinyl ethers, and various cyclic monomers. It features fast curing speed, low yellowing, excellent compatibility, and strong deep-curing capability.

Key Features:
- High reactivity with rapid acid generation
- Low yellowing, suitable for high-clarity systems
- Excellent compatibility with various monomer systems
- LED-responsive, suitable for 365–405 nm light sources
- Strong depth curing, ideal for thick coatings
