This printing ink, meeting the high requirements of the touch screen industry, is two component bright super-black insulation glass ink. The cured film has various advantages, such as good adhesion, water resistance, chemoresistance, printability, surface hardness and abradability.
Operation process: Add 12 portions of the TCB-100B hardener into 100 portions of this ink and dilute the mixture, then print with the 300-420 mesh halftone.
First coating: Baking at 160℃ for 10min; Second coating: Baking at 160℃ for 20min.
Technichal parameters are shown in the following table.

1. Performance features:
Its obvious predominance lies in environmental compliance, no irritative odor, excellent blackness, good thixotropic structure and
medium drying speed.
2. Usage:
1) Before use, add the matched TCB-100B hardener (in the proportion of 12%) and moderate thinner into the ink and then fully
stir the mixture before printing.
2) The recommended baking temperature is 160℃ and the recommended baking time is 10-15min. On other conditions, please
confirm the feasibility in advance in order not to affect the product quality.
3) During the multilayer overprint, in order to ensure the quality, the first coating solidifies after baking at 160℃ for 10min; the
second coating solidifies after baking at 160℃ for 20min.
4) The selection of the thinner types and the thinner dosage depend entirely on the adjustment of printing mesh number,
environmental condition and printing effect.
3. Storage condition:
Before and after using this series of ink, the ink containers should be kept completely sealed in cool and ventilated places to avoid
exposure to open fire and high temperature.
4. Guarantee period:
The guarantee period is one year since the production date. Beyond the deadline, please reconfirm the usability.
