Functionalize your surfaces with smart transparent coatings
HeiQ ECOS® uses a patented silver wire technology that is transparent and has excellent electrical properties. Coatings based on HeiQ ECOS® allow surface resistances of a few ohms to several megohms per unit area.
The stable, viscous dispersion of silver wires can be diluted in any ratio with water and short-chain alcohols. The dispersion is suitable for the production of electrically conductive varnishes and paints.
BENEFITS
- Transparent (up to 98% light transmission)

In the market: HeiQ ECOS
One of HeiQ ECOS® many ingenious applications turned out to be car window heating. Compared to the current state of the art, which utilizes printed lines on the surface of the glass, HeiQ ECOS® is transparent. The technology is easier to implement and results in a seamless final product. It’s especially useful when used on windshields and car windows as it offers immediate heating and fog dispersion without impairing visibility.
