Lord Adhesives PCC40579 Silver Conductor
Categories: Polymer; Thermoset; Epoxy; Epoxy, Electrically Conductive

Material Notes: LORD PCC40579 silver conductor is a one-component, thermosetting conductive epoxy designed primarily for surface mount attachment of electronic component devices.

Features: may be applied by screen printing, syringe or pin transfer. provides a working life of 3-5 days in a closed container at room temperature. Working life is reduced to 24 hours (25% increase in viscosity) if material is stored in an open container. rapidly cures between 150-200°C. cured film provides excellent electrical and mechanical properties with good bonding to a variety of substrates.
