MG Screen 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.

Dishwasher-resistant tests:
- Domestic dish washer: 600 cycles (65°C at 130 min for alkaline detergents)
- Commercial dishwashers, e.g. Winterhalter glass washer (85°C at 3 minutes): 700 washing cycles
Chemical Resistance:
- Perfume: G1-test after 24 hours;
- Ethanol and glass cleansing agent: 500 DRS;
- Aceton/MEK: 50 DRS.
Humidity resistance:
- 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.
