This printing ink, meeting the high requirements of the touch screen industry, is two component baking insulation glass ink. The cured film has various advantages, such as good adhesion, water resistance, chemoresistance, printability, surface hardness and abradability.

Scope of applications: common glass, chemically strengthened glass, and physically tempered glass.

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

              the 350~420-mesh halftone.

First coating: baking at 160℃ for 10 min;      Second coating:baking at 160℃ for 20 min.

Technichal parameters are shown in the following table.

Performance features:

Its obvious predominance lies in environmental compliance, no irritative odor, good surface tension, good thixotropic structure,

medium drying speed and weak corrosion.

Usage:

① Before use, add the matched TCB-100B 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 160℃ and the recommended baking time is 10~15 min. 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 20 min.

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.

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.

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.
