NoriGlass OR - Outdoor Resistant Screen Printing Ink

NoriGlass OR (outdoor resistant) is a new glossy silicone free 2-component glass screen printing enamel ink.

The outdoor resistant ink has been developed for the second surface decoration of glass, particularly for backlit displays of vending or ticket machines.

NoriGlass OR is easy to process and shows good resistances towards chemicals and mechanical abrasion.

The ink system shows low electrical conductivity, even the black color shades. Highly opaque black or white color shades and IR transparent colors are available as well.

NoriGlass TPI - Screen Printing Ink

NoriGlass TPI is a glossy silicone and halogen free 2-component glass screen printing ink.

The ink has been developed for the second surface decoration of glass, particularly for symbols of touch switches and for backlit displays, e.g. smart phone and tablet displays.

This organic enamel screen printing ink provides very high resistance to aqueous household cleaners, hand and machine dishwashing detergents as well as to chemicals and solvents like aliphatic and aromatic hydrocarbons, alcohols, greases and oils.

Besides its excellent resistances, the ink system shows low electrical conductivity, even the black color shades. Highly opaque deep black or brilliant white color shades are available from stock.

Aqua-Temp SIG

Aqua-Temp SIG is a new water-based stoving ink for glass decoration. The screen printing ink can be used for second surface printing of glass panels and displays for household appliances.
Printing substrates
Besides glass decoration (plates and flacons), Aqua-Temp SIG can be used as well for printing onto metals, ceramics and thermoset materials which resist the stoving process.
Screen open time is excellent, especially if the relative humidity in the printing room exceeds 50 %. Preferably it should be about 55 – 60 %. 
Recommended room temperature should be about 21 – 23 °C (69,8 – 73,4 °F).
Aqua-Temp SIG is based on organic binders. Therefore, the dried ink film does not resist scratching or pushing with hard, sharp edged objects. Final ink properties / resistances are achieved after the stoving process.
Each individual ink layer should be dried at 50 °C – 80 °C (122 °F – 176 °F), if two or more layers are printed.
Final stoving at 180 °C (356 °F) for 30 minutes of all ink layers must be applied.
Color shades
Black L 69250
White L 69290
Red L 69289
Protective Lacquer L 68742

Protective Lacquer / Hard Coat
Protective Lacquer L 68742 has been developed as final overprinting lacquer. The stoved screen printing lacquer shows excellent scratch resistances, comparable with hard coated surfaces. Subjacent ink layers are perfectly protected during the mounting process, e.g. glass panels for refrigerators.
The protective lacquer can also be used for overprinting of solvent-based ink systems (not yet stoved) such as NoriGlass TPI and ZK-Two-Component Ink.
