Sonotech Echogel
An Industry standard since 1974, ECHOGEL is an economically priced couplant for flaw inspection in volume use.ECHOGEL offers outstanding wetting capabilities and will quickly wet oily and dirty surfaces. ECHOGEL resists viscosity breakdown on salt-caked boiler surfaces. It is recommended for inspection of power generating boilers when salt cake is present.
ECHOGEL meets the Halogens and Sulfur requirements specified in NAVSHIPS MIL-STD-767. ECHOGEL meets ASTM F519 Hydrogen Embrittlement test on high strength steel.
