High reactivity under UV-A and visible light (365–405 nm), enabling rapid curing at low energy doses.
Excellent solubility in common acrylate monomers and oligomers, ensuring homogeneous formulation stability.
Low volatility and minimal odor, supporting safer handling and improved workplace air quality.
Good thermal stability up to 120°C, reducing premature decomposition during storage or processing.
Non-yellowing performance in clear and white coatings, preserving long-term optical clarity and color fidelity.
UV-curable inkjet inks for digital textile and packaging printing.
Optical adhesives used in display assembly and touch panel lamination.
Hard-coat formulations for plastic lenses, automotive interior trim, and electronic device covers.
3D printing resins requiring high resolution, low shrinkage, and excellent surface finish.
Wood and plastic varnishes where fast line speed and low-energy curing are critical.
