High reactivity under UV-A and visible light (365–405 nm) for rapid curing.
Low yellowing tendency, supporting excellent clarity and color stability in final coatings.
Good solubility in common acrylate monomers and oligomers, enabling homogeneous formulation.
Reduced odor and volatility compared to conventional α-hydroxyketone photoinitiators.
Excellent shelf stability in formulated systems at ambient storage conditions.
UV-curable clear and pigmented coatings for wood, plastic, and metal substrates.
Inkjet inks requiring low migration and high print fidelity on packaging and décor films.
3D printing resins (SLA/DLP) demanding precise depth control and surface resolution.
Adhesives and sealants for electronics assembly and optical bonding applications.
Overprint varnishes and functional topcoats in flexible packaging and label printing.
