- Chemical Composition
- RADGLO® RBA bases are composed of a solid solution of dyestuffs in a thermoplastic sulphonamide-melamineparaformaldehyde resin, dispersed in an alkyd resin.
- RADGLO® fluorescent pigments as such are not classified in the Color Index (CI), but certain color components are.

Technical Details & Test Data
- Lightfastness & Heatstability
- Lightfastness - Fluorescent pigments are more fugitive than conventional pigments. They are stable indoor light or outdoor conditions other than direct sunlight. By exposure to outdoor sunlight the color will change, whereby the degree fading is depending on following factors:
- Color of the pigment
- Pigment loading and thickness of the endproduct. The higher the pigmentloading and thickness, the better the lightfastness.
- Type of binderpolymer
- Intensity and angle of the incident sunlight. The lightfastness may be improved by including UV
- Absorber(s) in the formulation and/or by making use of clear overcoats containing UV-absorber(s).
- Heatstability - RADGLO® RBA series can be used for short dwell times in applications with processing temperatures up to 180°C without affecting the colouristic properties.
- Processing conditions & specific considerations
- colorSTRENGTH, BRIGHTNESS & FINISH - Innovative vehicle technology has given Radiant Color the ability to disperse a high loading of submicron fluorescent pigment particles in the RADGLO® RBA bases, and yet maintain a workable rheology.
- LOW ODOR - RADGLO® RBA bases contain hydrotreated ink oils. They have been formulated to produce low odor on the press, even when using infra-red lamps as drying assist. RADGLO® RBA bases can be used to formulate low odor inks for napkins, tableclothes and other items.
- PRESS PERFORMANCE - Sheetfed offset inks made from the RADGLO® RBA bases have been run on high speed sheetfed presses at 8 000 - 10 000 impressions per hour and are capable of much higher press speeds with excellent performance characteristics.
- EXTENDER VARNISHES - For optimum results, a low tack urethane is recommended. Optimum setting characteristics are developed with this varnish as well as optimum color brightness and mat finish. Always pretest the ink formulation for drying and adhesion on the stock to be printed.
- RUB & SLIP ADDITIVES - Where maximum setting speed and good rub resistance is required, the use of a high quality dry wax is recommended. Usually 2-3 % dry wax is sufficient. This permits the use of additional vehicles, oils and other modifiers which will contribute to faster setting speed, and improved printability and finish. Where maximum rub and slip properties are desired, the addition of 0.5 - 1.0 % PTFE-powder is recommended.
- DRIERS - A combination drier of 1% of 6% cerium and 1% of 8% manganese is recommended for sheetfed offset inks made from RBA bases. The addition of cobalt drier will accelerate the drying, but will darken the color and cause color instability. This condition is accentuated when heat is involved in the printing process or in ink storage.
- TACK REDUCING AGENTS - High boiling aliphatic oils such as Magiesol 52 are recommended as primary tack reducers. Optifilm Enhancer 300 and Tridecyl alcohol (TDA) are secondary tack reducers, but are much more effective in helping to control flow and transfer properties in the ink when used in small percentages. Drying oils such as tung, oiticica and linseed oil can also be used to reduce tack.
- ADDITIVES FOR WATER RESISTANCE AND ANTI EMULSIFICATION PROPERTIES - The RBA bases have been formulated to resist emulsification in most common ink formulations. Additional anti-emulsification additives should not be necessary.
- COMBINATIONS WITH NON-FLUORESCENT colorS - Small amounts of non-fluorescent color can be used effectively without significantly detracting from color brightness. Increases in color strength will usually compensate for any loss in brilliance. For example, 5 % Lake Red C flushed color added to 70-80 % RBA14 in the finished ink will result in a noticeable stronger ink without a significant change in the hue or brightness. Conversely, small amounts of RBA-bases can be added to conventional colors to help “clean up” the color. This has been found to be particularly effective when printing on uncoated paper stocks where the conventional inks lose color brightness when absorbed into the stock.
