Mara® Glass MGLA.
Impervious ink to weather conditions
The screen printing ink Mara® Glass MGLA is used for second surface decoration on glass for flat input systems used outside, or partly outside. This may include intercommunication systems, ship control systems, or vending machines. Solvent-based and two-component.
- Excellent for outdoor applications
- Suitable for lamination with very good bonding properties
- Good temperature resistance
- High opacity
Substrates:
- Glass

Ink adjustment:
If cleaning is carried out with automatic screen washing systems, we recommend prior to printing an additional manual cleaning with a fresh cleaner not having had any contact with ink residues containing silicone.
Drying:
Parallel to physical drying, i. e. the evaporation of the solvents used, the actual hardening of the ink film is caused by the chemical crosslinking reaction between ink and hardener. The drying times vary according to substrate, ink deposit, humidity, drying conditions, and the auxiliaries used.
For multi-colour printing, please note that the previously printed ink films should not be entirely cured before the consecutive ink film is printed on it. Only after all ink films have been applied, they should be baked.
The following values, related to the object temperature, concerning progressive cross-linking reactions (hardening) of the ink film (thickness 4 -12 µ) are recommended:
Intermediate drying: Overprintable after 3-5 min. / 160 -170°C
Final drying: 20 - 30 min. / 180 - 200°C

Mara Glass MGLA is made without the use of BPA/ BPS, and is silicone-free. For silicone-free products it is important to use only thoroughly cleaned stencils, squeegees, ink pumps, tubes (in the case of an automatic ink supply), and injectors for the manual ink filling of the stencil, etc.If cleaning is carried out with automatic screen washing systems, we recommend prior to printing an additional manual cleaning with a fresh cleaner not having had any contact with ink residues containing silicone.

Final drying: 20 - 30 min. / 180 - 200°CPrinting parameters:
All types of commercially available polyester fabrics and solvent-resistant stencils can be used. For a good opacity on coloured substrates, we recommend a mesh count between 68-64 and 100-48, for printing fine details 120-34 to 140-31. A suitable mesh count for thin ink films is 165-27.
