Conductive Surface Fillers for Electronics
A high silver content allows these surface fillers to conduct electricity and heat. Use them to fill gaps and rebuild missing material on electrical connections or to assemble new components. They come as two parts. The size listed is the combined total of the two parts.
Volume resistivity measures how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.
Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.
