  • Due to the possibilities of contamination with halogen compounds, 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 production: 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.

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.

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.
