Does someone know the low temperature resistivity of silver epoxy ? At room temperature it is around 10^-3 10^-4 ohm.cm, but around 4 K ?

I have contacted a sample (graphene) to wires (copper) with conductive epoxy (silver). At room temperature we measure a resistance around 50 ohm between the two end of the wires. But at 4 K in...
