Segmentation by Product Type

The UV photocuring agent market can be divided into two primary product categories based on their polymerization mechanism:

1. Free-radical Type

Free-radical type UV photocuring agents generate free radicals upon UV exposure, initiating the polymerization of acrylate and other unsaturated monomers. These agents are favored for their high reactivity, fast curing speeds, and compatibility with a wide range of formulations, making them suitable for high-volume production environments.

Market Insight: The free-radical type segment dominates the market, accounting for approximately 80% of global consumption in 2022. This leadership stems from their versatility in applications requiring quick curing, such as wood coatings and graphic arts. However, challenges like oxygen inhibition in open-air curing processes are prompting ongoing R&D to enhance performance through hybrid formulations.
Trend: With the expansion of 3D printing and digital manufacturing in Asia-Pacific regions, free-radical agents are seeing increased demand for resin-based applications. Manufacturers in China and South Korea are integrating these agents into automated lines to boost throughput, where cost-effectiveness plays a key role.

2. Cationic Type

Cationic type UV photocuring agents produce cations that trigger the ring-opening polymerization of epoxides and vinyl ethers. They offer advantages like insensitivity to oxygen inhibition and post-cure capabilities, which allow for deeper curing in thick layers or shadowed areas.

Market Insight: Although smaller than the free-radical segment, cationic agents are the fastest-growing category, projected to reach significant volumes by 2029 due to their superior adhesion and durability in electronics encapsulation. Their use in high-precision applications is gaining traction as industries prioritize reliability over speed.
Trend: The rise of flexible electronics and optoelectronic devices is fueling adoption in Europe and North America. For example, cationic agents are increasingly specified in LED manufacturing for their ability to cure under low-intensity light, aligning with energy-efficient production goals.
