Photoinitiator EDB is an efficient tertiary amine enhancer, often used in combination with free radical (Type II) photoinitiators to increase the initiation efficiency of the main photoinitiator. When used in combination with photoinitiators such as ITX and 907, it enhances the light absorption performance and improves the curing efficiency. It is suitable for offset printing inks, screen printing inks, solder mask inks, and adhesives.
Compared with conventional co-initiators, EDB offers superior compatibility, low volatility, and excellent performance in both pigmented and clear formulations.
Typical dosage: 1% – 5% depending on formulation requirements and photoinitiator system.
EDB functions as an electron donor in UV curing systems. When combined with Type II photoinitiators (e.g., benzophenone), it forms free radicals upon UV exposure, enabling efficient polymerization even under oxygen-rich conditions.
This mechanism makes EDB particularly effective in improving surface cure and reducing tackiness in UV coatings.
