NEW: Series 140-6125

New IR-transparent, silicone-free 2C screen printing ink for glass

Our new Series 140-6125 is a solvent-based, silicone-free, two-component screen printing ink based on highly resistant materials. Its characteristics enable excellent results from overprinting in technical applications – with our Series 632 glass printing ink, for example.

The printed ink film of Series 140-6125 is permeable to infrared rays but blocks visible light.

This makes Series 140-6125 ideal for the functional coating of components controlled by proximity sensors, such as infrared panels, screens and displays, and remote-controlled devices and systems.

Key characteristics

  • Maximum adhesion when combined with adhesives and decorative inks
  • Transmits infrared rays, blocks visible light
  • Excellent resistance
  • Easy-to-operate system
  • Modern, silicone-free formulation

Most suitable applications

  • Optimized for demanding flat glass applications
  • Perfect for infrared panels, screens and displays
  • Ideal for glass cover plates
  • Consumer electronics: cover plates, screens
  • Household electronics: kitchen utensils, scales
  • Telecommunications: cell phones, set-top boxes

Transmission spectrum

Figure 1 shows that Series 140-6125 has very high opacity in the visible light spectrum with very good IR transparency; the x-axis shows the light transmission in %, the y-axis the wavelength of the light λ in nanometers (nm):

Application with a 43.80 Y mesh is not suitable for all sensors due to the reduced IR transparency; however, it may be useful for special applications (e.g. curing an IR-sensitive adhesive through the ink layer).
