Two component pad-printing ink, specially suited to print on “difficult substrates” such as metals, glass, ceramics, wood and enamels.

21 SERIES - excellent ink pick-up and ink transfer from the pad. Discharges very well onto the substrate. The dried film of the 21 SERIES has great chemical resistance and great adhesion on the substrate.

Recommended applications: Metal, glass, ceramics, acetal pens/lighters, polyamides, treated polyethylene and/or polypropylene, woods, etc.

Finish: Gloss.

Presentation: Only viscosity needs to be adjusted, depending on the job, factory temperature and print speed.

Catalization: Add to the ink HARDENER-118 at 7-14%, depending on the material which is going to be printed.

Diluents: D-100 as fast and D-400 as normal to slow. Correct mixture gives  good behaviour, in the ink cup or inkwell. When air dried, it dries in a few minutes if the temperature of the factory is above 20ºC and there is good ventilation. When dried by oven, at 80ºC, it dries in about 2-3 minutes. In any case, ovening drying is very important to assure a good polymerisation.

Colours:       See table COLOURS/SERIES

Any other colour can be formulated on demand.

Other observations: Occasionally, when the material wets very bad, it is convinient to add a drop of additive 29100 Smoother LF.
