High Sensitivity Cationic Photoinitiator

Uyracure-2500L is a new type of cationic iodonium salt photoinitiator. By adding special photosensitive materials, the absorption wavelength is greatly increased and it has excellent photosensitivity. It has outstanding performance in acid-generating activity and long-wave absorption under different light source conditions. The cured coating does not yellow, release no benzene and has excellent curing performance. It is especially recommended for curing cationic colored systems, especially ink applications with high carbon black content, and provides strong support for the application and expansion of cationic curing products. Because the long-wave absorption efficiency is improved, care should be taken to avoid light during production, processing and use. Taking into account the economy of the product formula, it is recommended to use it with Uyracure-1600L initiator.

In the microelectronics and semiconductor industries, they are used to cure photoresists, photoresists, and other light-sensitive materials to make microelectronic devices . In 3D printing, highly sensitive cationic photoinitiators are used to achieve rapid layer-by-layer curing to speed up the printing process. Recommended dosage: 1-4% for clear coating, 4-6% for black coating.
