CHO-BOND 360-20 is a two component, silver plated, copper filled, electrically conductive, general purpose epoxy adhesive
CHO-BOND 360-20 is a two-component, silver plated copper filled conductive epoxy adhesive designed for applications where a strong, conductive electrical bond must be achieved. The silver copper filler of CHO-BOND 360-20 provides a cost effective alternative to pure silver filled conductive epoxies in applications where moderate conductivity is acceptable. This thick paste is good for filling rather large bond lines and cracks (0.004 inches -0.025 inches) of electrical boxes and enclosures. Curing of CHO-BOND 360-20 can be achieved in as little as 15 minutes with heat to minimize equipment downtime and increase manufacturing throughput. The 1:1 weight mix ratio makes CHO-BOND 360-20 easy to handle and use. Typical applications include poorly tolerance enclosures or castings, EMI vents and windows, and vertical and overhead fillet applications.
