Printing ink hardeners
There are three hardeners available for this glass pad printing ink. These are the i-267x, i-260x, i-240x, and i-247x. The i-267x is the most popular printing hardener for the MG ink series. The i-247x speeds up the ink’s reaction and reduces the gloss effect of the ink film.

- Perfume: G1-test after 24 hours;
- Ethanol and glass cleansing agent: 500 DRS;
- Aceton/MEK: 50 DRS.
- Condensation water test (75 °C at 100% RH for 30 minutes; cold water immersion test for 24 hours). Learn more about printing applications for this food safe ink for pad printing.
