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):
Figure 1 Opacity achieved and IR transparency with different meshes (clear varnish + colorant 70:30 with 3 % Series 600-HVA)
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).
