UV Curing Ink for Electronics
CAS Number: 7473-98-5
UV curing ink for electronics is a radiation-curable formulation used in inkjet or screen printing of functional layers on PCBs, flexible circuits, and electronic substrates. It cures instantly under UV or LED-UV irradiation, enabling high-throughput production of solder masks, dielectric layers, and decorative markings. Designed for excellent adhesion to copper and laminate surfaces with high chemical resistance after cure.
