Description
Radiant RBU Series Fluorescent Ink Base
Radiant RBU Series is a formaldehyde-free, daylight and UV-responsive fluorescent ink base developed for energy-curable printing applications. It is specifically designed for UV/EB-curable flexographic and lithographic inks, where bright fluorescent colour, gloss and print performance are required.
Key Features
- Pigment Concentration: 45–55%
- Formaldehyde: Free
- VOC: None
- Specific Gravity: Approx. 1.20 g/ml
- Processing Temperature: ≤40°C
- Response: Daylight & UV

Applications
Radiant RBU Series is suitable for UV/EB flexographic and lithographic printing inks. It can be formulated with suitable resins and photoinitiators to develop finished energy-curable fluorescent inks.
The series offers bright fluorescent shades with a glossy appearance and is designed for applications where energy-curing, colour intensity and print quality are important.
Technical Note
RBU is supplied as an ink base rather than a finished printing ink. The final formulation should be optimized according to the selected resin, photoinitiator, substrate and curing conditions. Processing temperatures should be maintained at 40°C or below. (Fluorence TDS)
