CHO-BOND 584-29 is a two component, silver filled, epoxy adhesive system
CHO-BOND 584-29 is a two-component, silver filled conductive epoxy adhesive system designed for applications where a strong, highly conductive electrical bond must be achieved. CHO-BOND 584-29 is recommended for relatively small bond lines (less than 0.010 inches (0.25mm)), but can be used for larger bond lines in applications where vibration or potential for cracking is not an issue. The fine silver filler of CHO-BOND 584-29 make it a good material choice for precise application in and around tight spaces and electrical components. CHO-BOND 584-29 comes in a variety of sizes and packaging so customers can choose a package and material size which is right for their application, minimizing material scrap and mixing issues. Curing of CHO-BOND 584-29 can be achieved in as little as 15 minutes with heat to minimize equipment downtime and increase manufacturing throughput. Typical applications include bonding and grounding of electrical components, cold soldering, and bonding and sealing machined enclosures.
