Photoinitiator 379
2-Dimethylamino-2-(4-methylbenzyl)-1-(4-morpholinophenyl)-1-butanone
The liquid amino ketone — easy dosing with LED-friendly absorption.
Product Description
Photoinitiator 379 is the p-methylbenzyl analog of 369, supplied as a pale yellow crystalline-to-liquid grade that dissolves readily in acrylate oligomers. Its absorption profile closely matches UV LED emission at 385–405 nm while retaining full mercury-lamp activity.
The liquid handling advantage makes 379 convenient for inkjet and low-viscosity formulations where powder dissolution is impractical. Typical loadings are 1–4 wt% alone or in combination with TPO-L and ITX.
Key Features
- Liquid handling — no powder dissolution step
- UV LED responsive (385–405 nm)
- Low odor suitable for packaging inks
- Excellent compatibility with acrylate systems
Applications
- UV LED inkjet inks
- Flexographic and offset UV inks
- Overprint varnishes
- UV adhesives
