Etch Resist

Digital printing of an etch resist solution can revolutionize the production of components where an acid etch process is used. The highly accurate placement of the etch resist allows complex patterns and high precision and small detail areas to be worked on, transforming expensive and highly wasteful processes in applications such as lamination press plates, fabrication of LCDs and the growing EMI and RFI shielding market. Solutions may also be possible for dielectric insulation, offering huge benefits in many applications.

Sensient’s pioneering etch resist ink, Xennia Pyrite, is a UV curable solution offering outstanding performance in acid etch processes and allowing highly detailed patterned areas to remain while non-printed areas are removed through the etching process.
