790 is a quick drying, stamping ink developed especially for plastics.
It is colour fast, weather-proof and has good resistance to alcohol. For this reason, 790 is particularly suitable for marking electronic circuit boards which are frequently washed with isopropanol for final cleaning. If such rapid drying times are not required, the delay agent 790 can be added.
We also recommend 790 for marking lacquers and waxed cardboard. The translucent types 790 are preferable for light backgrounds; the pigmented versions for dark backgrounds. Suitability tests should be carried out because too many different qualities are available on the market to allow a reliable recommendation.

We recommend felt plate pads for 790. On automatic stamping machines, systems with ink reservoir are preferable.
