High reactivity under long-wavelength UV-A (320–400 nm) irradiation, enabling efficient curing with LED-UV sources.
Low migration and excellent extractable residue profile, supporting compliance with stringent food-contact and medical device regulations.
Excellent solubility in acrylate monomers and oligomers, ensuring homogeneous formulation without crystallization or phase separation.
Reduced yellowing tendency compared to conventional Type II photoinitiators, preserving clarity and color fidelity in transparent coatings.
Thermally stable up to 120 °C, allowing safe incorporation during hot-melt or high-shear processing.
LED-UV curable inkjet inks for packaging and decorative printing.
Clear protective coatings on plastic substrates (e.g., PET, PC, ABS) requiring low-yellowing performance.
Adhesives for electronics assembly and optical bonding where low outgassing and high transparency are critical.
3D printing resins (SLA/DLP) demanding rapid surface cure and minimal post-cure odor.
Medical device coatings compliant with ISO 10993-5 and USP Class VI requirements.
