AK22: Covering Material for Strain Gauges — Strongly Adhering kneadable Putty

AK22 is a tough, kneadable putty that adheres to virtually any material. The putty is kneaded by hand onto the measuring point. It is recommended to use AK22 covering putty along with ABM75 aluminum foil, or even with a third layer of SG250 silicone rubber, to achieve optimal measuring point protection in many applications.

Please note that very high acceleration (e.g. rotation) might damage the AK22 covering putty due to its mass.

AK22 covering material for strain gauges can be stored at room temperature for approximately 2 years.

  • AK22: Malleable and kneadable compound covering material for strain gauges
  • Temperature range: –30°C to 120°C (–22°F to +167°F)
  • Application: Pressing on by hand
  • 1-AK22: 1 kg pack; sufficient for approximately 30 strain gauges*

*The specified quantities are intended for reference only, since covering material consumption depends, among other things, on the size of the strain gauges that are used.
