Conductive bonding brokers play a basic function in making certain dependable electrical connectivity in lots of electromechanical assemblies designed to function on the extremes of temperature and stress of area. Failure of a single bond between conductive parts in an meeting can ripple quickly by mechanical and electrical programs, in the end threatening spacecraft integrity and crew security. In two purposes, Grasp Bond EP21TDCS-LO conductive epoxy met crucial necessities for sustaining sturdy bonds in electromechanical programs meant to function in area circumstances.
Grasp Bond Polymer System EP21TDCS-LO is a two part, silver-filled epoxy designed to make sure high-strength conductive bonds between dissimilar supplies at temperatures right down to 4K. In contrast to most two-part silver-filled adhesives, Grasp Bond EP21TDCS-LO makes use of a easy one-to-one combine ratio that continues to be workable for 30-40 minutes and cures at room temperature in 24-48 hours or in 1-2 hours at 200°F. With quantity resistivity lower than 10-3 ohm-cm, this adhesive cures to an electrically conductive bond that mixes excessive energy (shear energy over 850 psi) and adaptability (T-peel energy over 5 kilos per linear inch) – properties uncommon in a silver epoxy. Together with its workability and efficiency traits, Grasp Bond EP21TDCS-LO meets crucial necessities for area operations together with passing NASA low-outgassing take a look at standards.
The purposes listed within the desk under spotlight use of Grasp Bond EP21TDCS-LO in making certain high-strength, conductive bonds in assemblies designed to outlive the cruel circumstances of area.
