Echogel

Economical Ultrasonic Couplant

Echogel® 20 is an economical, basic-use couplant in medium-thick gel viscosity for ultrasonic inspections, like flaw detection/sizing and thickness gauging, where salt cake or metal corrosion salts are present. It provides good corrosion inhibition and resists viscosity breakdown on salt-caked boilers and other corroded materials.

Benefits

  • Enhanced surface wetting to quickly cover oily or dirty surfaces
  • Maintains viscosity on corrosion or salt cake
  • Good corrosion inhibition
  • Silicone free
  • Hydrogen embrittlement testing
