UV Curable Flexo Ink
CHARACTERISTIC
The inks are especially developed for printing on various different flexo machines.
PROPERTIES
- Excellent printability
- Fast curing
- Good gloss, high colour strength
- Viscosity properties fit for flexo printing
- Low odour
- Optimal resistance properties will be obtained 24 hours after printing
- Formulated without benzophenone
APPLICATION AREA
- All flexo label and packaging printing machines equipped with a UV-curing system.
UV CURING SPEED (with 2 lamps of 120 W/cm)
- 200 m/min
(the reactivity is also influenced by the substrate, the condition of the lamps, the condition and adjustment of the reflectors, the thickness of the ink layer, colour, etc.)
SUITABLE SUBSTRATES (surface tension see ‘Recommended treatment levels’)
- All kinds of paper and board
- Inline Corona treated polyethylene
- Selected laquered/primered aluminium foils and lids.
Preliminary adhesion tests are recommended

REMARKS
- When laminated afterwards, take care to use the correct fast inks, and to do a preliminary adhesion test.
- Cleaning: it is not necessary to wash the press immediately after printing. The UVFL01-series will not cure in the press and is therefore ready to use for the next day’s printing. However, the ink may start to cure in the press if sunlight or UV-light from the bulbs / UV-lamp is allowed to shine on the ink.
- Shelf life: the UVFL01-series has a 12-month shelf life guarantee. This guarantee covers 12 months from the date of manufacture (which is mentioned on the label). In order to give this guarantee, certain recommendations must be followed: the UVFL01-series should be kept on stock at temperatures between 15 – 20°C and they should not be exposed to direct sunlight or heat. If possible, store the ink in a dark room.
- Rollers: the following roller material is recommended: EPDM (Ethylene-Propylene-Diene-Monomers). EPDM rollers show excellent performance with UV-inks.
- Certain metallic UV-inks may cause swelling of EPDM rollers.
- Nitrile rubber: nitrile rubber rollers show minimal swelling with UV-inks and conventional inks. Solvents such as glycol and acetates do have a tendency to make this rubber swell. Nitrile rubber is recommended when using two component metallic inks.
