Polymer thick film inks
Membrane switches and keyboards

Inks for membrane switch and keyboard applications.

Ag 515 EI is a silver-based thermoplastic ink composition formulated to offer a screen-printable conductor for circuit printing. Typical applications include membrane switches, flexible circuits and touch screens, and many more. The high conductivity of Ag 515 EI enables narrower lines and longer circuit tracks without compromising overall conductivity..

D 150 EI is a 100% UV composition mainly designed to protect printed electrodes from natural light and mechanical abrasion. After polymerization, D 150 EI presents good adhesion on difficult substrates like untreated PET and plastics in general, combined with flexibility, transparency and appropriate dielectric strength.

C 800 EI is a high-purity carbon/graphite-based thermoplastic ink composition formulated to offer a screen-printable conductor for circuit deposition. Typical applications include membrane switches, flex circuits and touch screens. C 800 EI is typically used as a protective coating to mitigate electrostatic discharge, silver migration and chemical attack. It can be mixed with Ag 515 EI to achieve finely-tuned conductivity values.

D 100 EI is a 100% solid UV composition designed for producing flexible and rigid circuits. After polymerization, D 100 EI shows excellent adhesive properties on difficult substrates like untreated PET and plastics in general, combined with superior flexibility. The extremely pure and finely dispersed minerals ensure a high level of thermal and electrical insulation. D 100 EI is designed to resist mechanical post-processing like cutting and puncturing.
