- Halogen（Chlorine Cl, Bromine Br）compounds and naphthalene are not intentionally used in raw materials.
- A wide range of color variation enables the creation of colorful printed materials.
- It has excellent adhesion to glass and various types of resistance, and it can be used in a wide range of fields.
- Glass plate
- Z-705 SOLVENT (slow)10％
- Dilution 3 to 10%
- *Do not use other solvents as they may cause contamination of halogen and PAHs and may adversely affect curing, adhesion, stencil stability, or other properties.
Catalyst, Promoter mixing
- Be sure to add 0.5% of GLS GLASS PROMOTER
- Pot life: 3 to 6 hrs.
- *The ink will not turn to gel after the pot life has expired. Due to its poor adhesion and resistance, be sure to mix only enough to use.
- SM-40 DEFOAMER 0 to 2%（For anti-foam and improvement in leveling）
- NF-003 SOLVENT
- T 200 to 350 mesh（Coverage would be 35m2/kg at 250 mesh）

- As Halogen compounds and polycyclic aromatic hydrocarbons (PAHs) may be mixed in the ink, only designated Solvents and Catalysts can be used.
- Please check the squeegee rubber, emulsion, materials and substrates before use, as they may contain halogen compounds.
- Checking before commercialization: Adhesion and resistance properties may change due to differences in substrates, processes, printing and drying conditions. Be sure to check the adhesiveness and resistance properties before mass production printing
- Ink shelf life: 12 months from production date, unopened.
- UN No.: Not classified in the definition
- UN Classification: Not classified in the definition
- Use safety gloves and eyeglasses to protect skin and eyes. If the ink comes in contact with skin, wash with soap and plenty of water（or lukewarm water）and consult with a doctor.
- Containers should be closed tightly after use and stored in a cool and dark place.
- SDS is available upon request. Please request a copy and read it carefully before handling the products.

What are screen inks for glass substrate printing? And what are their characteristics?
For printing on glass substrate, GLS-HF ink series , a two component type Halogen Free ink for printing on glass substrates is recommended.
The GLS-HF ink series is characterized by the fact that it is an organic ink, unlike the inorganic inks conventionally used for glass substrate printing.
Therefore, GLS-HF ink has excellent functions to solve the problems of inorganic inks (burning type ink) such as “lack of color variation” and “environmentally hazardous substances”, etc.
Introduction of GLS-HF ink (1)
Is there any information related to the high value-added flat panel and touch panel?
We would like to introduce the high value-added glass substrates for flat panels, touch panels, etc. using the technologies we offer.
From a design stand point: *Realize various color variations on glass substrates. *High opacity Black and high opacity White that can be applied to window flame of touch panels.
From a function stand point: *Providing IR transmittance functions, *Malfunction prevention by non-conductive black, *Reduction of environmentally hazardous substances, etc.
What are the meanings of X and Q used in the ink names such as IPX, INQ, FMX, etc.?
X and Q are used to designate isophorone-free inks.
What is non-conductive black ink?
Non-Conductive Black Ink is an ink that has a high electrical resistance of the printed ink layer, and has both a function that is difficult for electricity to pass through and a high opaque black color. The high electrical resistance (low conductivity) prevents malfunctions and failures of electronic components, etc., caused by electric current flowing through the printed ink layer. Furthermore, its high opacity makes it suitable for printing on flat panels and smartphone displays that require light-shielding properties.
Introduction of Functional Black Ink
What is high opacity black and white?
This function provides a beautiful black or white color with high opacity even in environments where backlights are used, such as outer frames of flat panels and touch panels.
