CG-203B is a black ink specially developed and designed for glass substrates by Chenguang (Changzhou) New Material Technology Co., Ltd. with excellent covering effect, excellent construction workmanship, very high mechanical strength, stable chemical weathering, which can be used in the fields of photovoltaic glass, architectural glass, and decorative glass. This product is based on inorganic connecting material (glass powder), inorganic pigment (copper chrome black, etc.), as well as water-based resin compounding process, with aqueous solvent as the dispersion medium, the use of dispersion wrapping technology, can be constructed on the surface of the glass dense glass-colouring material glaze layer; the product's solid content, viscosity, fineness, and other indicators can be customized according to customer needs, in addition to the product adopts relatively environmentally friendly formula system, has passed the RoHS certification. The product has passed RoHS and other certificates. The preferred coating method for this product is screen printing process, also suitable for roller coating, spraying and other processes. After completing the coating process of CG-203B ink, the corresponding glass should be heat-treated to make the coating surface of the glass surface dry, and then go through high temperature tempering treatment to achieve the final performance of CG-203B ink. It is recommended that the tempering temperature should be above 690℃ (high temperature zone) and the tempering time should be 90-110s; the conventional thermal tempering process for flat glass can meet the heat treatment requirements of CG-203B. CG-203B ink has excellent construction process window, and the covering performance of coated glass can be changed by adjusting the coating thickness. The required coverage will vary depending on the application area. Typical coating wet film thickness is 18-25um. In addition Chen Guang can provide technical information packages for detailed application of the inks under various process conditions.
