IJ series is purely transparent silver ink designed by InkTec’s outstanding technology and research team. This silver ink is different from other existing conductive inks based on nano-technology because InkTec’s Silver Injet ink is not formulated by particle structure, so it is stable even in normal temperatures, which makes it eminently useful for various applications within the electronic industry.

InkTec mirror coating ink is a new metallic ink developed by our original technology. Different from the conventional plating process, it dose not generate waste water in the coating process so that the emission of pollution can be avoided and products can be manufactured at high speed. And our coating inks can be applied to various coating methods such as Roll to Roll, Spray and Dip because its viscosity is easily adjustable to prevailing production conditions. Our superior coating inks can be applied to cars, home appliances, buildings, and can create whatever mirror effect is required.

Comparison of Coating Process

Cost Low cost (Raw material cost low & existing facilities can be used) Low cost Costly due to initial facility investment

Production Efficiency Fast production & Simple process Not bed Low production efficiency

Environmental Friendly Production Environmental friendly without generating waste water Use much water/ Use large amount of toxic substances Environment friendly

Quality of finished product Good metallic feel Various metallic feel but low quality (blot lnferiority) Even merallic feel

InkTec Printing Ink is a conductive silver ink for flexo, graphic, and gravure printing. It is suitable for high value-added products which have technical limitations such as low temperature, microelectrode and resistivity. These printing inks can give you a competitive edge in this aggressive market. Product Features Fine Pattern with Superior Conductivity TEC-PR series inks have high density after sintering since they have very few gaps between particles. For this reason, our TEC-PR ink can produce fine patterns with high conductivity. Short Sintering Times in Low-temperature The brief sintering time in low temperatures of our silver ink means productivity is improved by about 5min at 140°C, which generates High Electrical Conductivity. Controllable Viscosity according to Application Depending on the customer’s printing methods and applied substrates, we will happily provide the inks adjusted to the viscosity the customer requires.
