2. UV vs. EB: How do they work?
| Technology | Key Features |
|---|---|
| UV (Ultraviolet) curing | Uses UV lamps (arc, LED, excimer) to trigger polymerization in photosensitive resins; ideal for thinner films and rapid pass‑by cure. |
| EB (Electron Beam) curing | Uses high-energy electrons to crosslink thermosetting resins volume-wise; effective for thicker opaque coatings without photoinitiators. |
Both technologies allow retrofitting existing coil lines. According to panels at RadTech 2024, coil lines can be upgraded to include UV or EB units instead of large ovens—often without reducing throughput—with benefits ranging from space savings to process simplification.
