General description

SunTronic Conductive Silver Ink AST6025 is a screen printable conductive ink specifically designed for printing fine line and fine pitch conductive traces.
The ink exhibits high viscosity, low slumping, excellent conductivity and environmental stability, and adhesion to various substrates, including glass, various metals, PET, and transparent conductive films.
AST6025 is specifically suitable for printing of fine interconnects, printed RF antennae, and bus bars for touch panels.


Typical drying temperature may range from 120-200°C (248-392°F) depending on temperature tolerance of the substrate.Drying time may range from 2-30 minutes.Higher drying temperature and/or longer drying times will result in better electrical performance, adhesion and mechanical properties.
Optimum drying conditions should be established for particular equipment used by the customer.
AST6025 is supplied as ready-to-use ink. It should be stirred well prior to printing. AST6025 is suitable for use on hand, semi-automatic or fully automatic screen printing machines.
Typically, polyester or stainless screens with mesh count 325-430 threads/inch can be used depending on desired ink film thickness and resolution. For fine lines between 100 - 250 microns nominal line width, stainless screen mesh is preferred with mesh count between 325-400 threads/inch. For <100 microns line widths, 430 and higher stainless steel mesh counts are recommended.
