Silver Conductive Epoxy, H-20E EPO-TEK®

Two component, silver filled, epoxy system consisting of a silver resin paste and a silver resin hardener (1:1). It is a smooth, thixotropic paste, 100% solids system characterized by outstanding high temperature properties and excellent solvent, chemical and moisture resistance. It has a long pot life and is fast curing at relatively low temperatures.

Will withstand 200°C for 1,000 hours. Containing no solvents or thinners, it will not outgas. H20E is ideal for electronic applications. Cures rapidly. Easy to use; the pure silver powder is dispersed in both the resin and the hardener so that it can be used in a convenient 1:1 mixing ratio. Non-toxic – complies with USP Class VI Biocompatibility standards.

NASA approved – passes NASA low outgassing standard ASTM E595 with proper cure. Ref: http://outgassing.nasa.gov.
