Galaxy® MCI 2500 High Speed UV-Inks have been specifically developed for colour-coding of optical fibres with a higher processing speed ( fast cure response ) due to High Flow Additives and giving a higher intensity & brightness of the colour shade on the fibre. Galaxy® MCI 2500 High Speed UV-Inks are according to IEC 60304, EIA/TIA-Munsell and according to ”Deutsche Telekom” F.T.Z. standards.

Galaxy® MCI 2500 High Speed UV-Ink is the successor of the world wide known and accepted Galaxy® MCI 2000 UV Ink, which is a result of a over 15 years experience in the manufacturing and processing of UV-Inks & Coatings.

Galaxy® MCI 2500 High Speed UV Inks are available in 12 bright & glossy standard Colours as well as Colourless (Clear - 513). Additional 11 Special Colours to complete 24 Colour shades are available.

According to ROHS 2002/95/EG, Galaxy® MCI 2500 High Speed UV Inks are free from the following substances:

  • Lead - Chrome(VI)
  • Mercury - Polybromed Biphenyle (PBB)
  • Cadmium - Polybromed Diphenylether (PBDE)

Colouring Process:

The Galaxy® MCI 2500 High Speed UV Inks should be treated according to the Processing
Guideline before using in the colouring process to assure continuous high quality results.
Curing of the ink is accomplished with the aid of UV radiation.
The cure is performed with UV light in the range of 240-420 nm such as fusion UV curing system
(F300-D Lamp, 120W/cm) with a speed of 250-300 m/min per lamp,
(F450-D Lamp, 120W/cm) with a speed of 450-500 m/min per lamp,
(F600-D Lamp, 240W/cm) with a speed of 700-750 m/min per lamp,
on Delachaux colouring line (3 fusion F600-D Lamps) with a speed of 2200 m/ min,
on Nextrom colouring line OFC 52 (3 fusion F600-D Lamps) with a speed of 2100 m/ min and
on Medek & Schörner colouring line GFP-H (2 M550 FZ lamps) with a speed of 2100 m/min for a
coloured layer thickness of 5.0 μm. Care should be exercised so that the coloured fibre is aligned in the
focal point of the UV-lamp.

Galaxy® MCI 2500 UV inks can be used in on-line as well as in off-line colouring process.

Shelf life:

COIA’s Galaxy® MCI 2500 have a shelf life of 24 months when stored at temperatures not higher than
25°C in a low humidity dry place according to MSDS. At the same time, the products should be
protected from all sources of ultraviolet light, including sunlight and fluorescent light. Note that storage
at elevated temperature may cause a light phase separation.
