Printing Inks for Glass

Made in Germany

Most of the organic inks for Glass are 2K (two-part reaction) inks and require post-heating process. However in summersmost inks are easier to use. In winters/Rain season a typical problem is of dew or moisture formation on the surface of glass poses a problem of adhesion. Hence the ink system must be able to work in summer and winter.The natural surface tension of some glass doesn’t allow quick bonding thus arising the need of adhesion promoters. 

Printing on Glass is a very difficult subject especially with solvent based organic ink systems. RUCO has a very successful program for this since last 30 years.

RUCO inks are free from heavy metals are dish washer safe and chemical resistant. Inks can be applied either by Screen Printing, Pad Printing,Spray Coating or Roller Coating. 

• EPOXY and PU based ink systems work best on glass.
• Solvent Based Solutions
• Screen/Pad

RUCO T01 Series: Made in Germany

This glossy, physically drying, chemically reactive pad &screen-printing ink exhibits good mechanical and chemical resistance, as well as a good flexibility. The colour shades of series T01 are light fast, weather resistant and guarantee high opacity. Higher temperature 150°c-180°c for 30 minutes gives very good dishwashing and chemical resistance. 

Ink Type: Two-part reaction

Substrate: Glass, acrylic glass, lacquered surfaces, metal, thermosets, PE PP

Finish: High Gloss

Mixing Ratio:  Add hardener (100VR1294) to the main agent at the ratio at 1:10 and agitate them well before use. Use with in the pot life 6-8 hours after which the mixture will turn to gel or lose its designed physical properties.

Diluent:  Use the following solvents (15:25% weight) to adjust viscosity: standard solvent (38571), fast dry (35353) and for Glass (100VR1390), retarder for screen printing 34392,35696

Drying Time:  Natural and Thermal curing. Sets to touch in 5 minutes at room temperature at 21°c. While adding hardener to the ink, drying of the ink will take approximately 36 hours at room temperature. To accelerate the ink drying onto the substrate the use of hot air blower or infrared lamps is recommended. Heat treatment at 150°c for 30 minutes is recommended for the best result.

Applications Cosmetic containers like bottles of perfume and oil. (T 28,110GE, T-01/10kk) Touch Panels, Capacitive Touch Panels of electronic devices. (T-01/10kk halogen free) Acid wash effect ink and coating Over foiling or Inline foiling   RUCO Inks have an interesting organic ink solution to replace the toxic and dangerous acid etch which is done by Hydrogen Fluoride Acid (halogen-free acid). Applications are done by spray coating or screen printing. A special inline screen-printing ink is screen printed followed by foiling only on the screen-printed surface.

RUCO T28 Series: Made in Germany

Many users do not have the facility to post heat glass for a long time so T28 is made for such applications where curing speed is fast. Heating required is 120°C just for 10 minutes. However, the adhesion level is improved with the passage of 72 hours.

Caution: Higher temperature than (120°C) makes the ink matt.
