TEC is the acronym for “Transparent Electronic Conductive,” and one of the salient features of that TEC ink is that it is purely transparent in the liquid form before sintering. TEC ink is unique because it is not formulated by particle structure.
Silver TEC ink is stable even in long-term storage and can be applied to various substrates because it enables ink sintering in low temperatures for conductive traces.

Advanced manufacturing method
: Soluble Silver Cluster & Complex type

Reduction of the raw materials(Ag)
: Forming the thin layer compared to the others

Low temperature sintering (Less than 120°C)
: Applicable to heat-weak substrates

Thin film & High Conductivity after short sintering time

High stability and long-term storage

IJ series is purely transparent silver ink designed by InkTecs outstanding technology and research team. This silver ink is different from other existing conductive inks based on nano-technology because InkTecs 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 coating process so that it can make you avoid pollution conflicts and manufacture products at high speed. And our coating inks can be applied various coating methods such as Roll to Roll, Spray and dip since it is easily adjustable viscosity according to the production conditions. Cars, home appliances, architecture and whatever mirror effect is needed, our superior coating inks can be applied to.

InkTec Printing Ink is a conductive silver ink for flexo 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 140C, which generates High Electrical Conductivity.

Controllable Viscosity according to Application
Depending on the customers printing methods and applied substrates, we will happily provide the inks adjusted to the viscosity the customer requires.
