Screenable Silver Paste For Membrane Switches

Our range of Screenable Silver paste For Membrane Switches is a heat-drying electrically conductive paste designed for membrane switches. It through making silver, choosing high molecular polymer resin, solvent and additive, modification research, solved the relation between high adhesion of film and heat-drying, and the problem between homogenization of thin-layer and change of film shape. This product has features of low heat-drying temperature(60i 120a ), short-drying time(20i 30min), low resistivity, good adhesion, superior abrasion resistance and creasability.
