Abstract
A resistive composition for screen printing onto a substrate. The resistive composition, based on total composition has a) 5-30 wt. % of polymer resin, b) greater than 0 up to and including 10 wt. % of thermosetting resin, c) 10-30 wt. % conductive particles selected from the group consisting of carbon black, graphite and mixtures thereof and d) 0.025-20 wt. % carbon nanoparticles, wherein all of (a), (b), (c) and (d) are dispersed in a 60-80 wt. % organic solvent.
