This printing ink is two component baking glass ink, aiming at meeting the high requirements of the specific touch screen industry. It has various advantages, such as good adhesion, excellent physical and chemical resistance. Its obvious predominance lies in high surface tension and good thixotropic structure.

Scope of application: Reinforced PMMA, PC and PET sheet of Mobile phones, navigators, LCD TV, etc.; some electroplating

material, PET sheet, reinforced glass, OGS secondary cover, etc..

     Operation process: Add 10 portions of the TCB-200B hardener into 100 portions of this ink and dilute the mixture, then print with 

                      the 350-420 mesh halftone.

Drying condition: 150℃×20min.

Technichal parameters are shown in the following table. (Take the black ink of this series as an example.)

 1. Usage:

1) Before use, add the matched TCB-200B hardener (in the proportion of 10%) and moderate thinner into the ink and then fully 

  stir the mixture before printing. 

    2) The recommended baking temperature is 150℃ and the recommended baking time is 20-30min. 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 150℃ for 10min; the 

  second coating solidifies after baking at 150℃ for 15min; and the last coating solidifies after baking at 150℃ for 20-30min.

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.

2. 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. 

3. Guarantee period:

  The guarantee period is one year since the production date. Beyond the deadline, please reconfirm the usability.

Note 1: All the above tolerance test data, derived from our test results, is for your reference only and not listed as guarantee value.

Note 2: This series of ink meets the standard of RoHS2.0, REACH, Halogen and all of the test data concerning eight heavy metals.
