Economical Ultrasonic Couplant
Echogel® serves as an economical, basic-use couplant ideal for ultrasonic inspections, including flaw detection, sizing, and thickness gauging, particularly in environments where salt cake or metal corrosion salts are present. It offers excellent corrosion inhibition and resists viscosity breakdown, making it suitable for salt-caked boilers and other corroded materials.
Available in two viscosities, Echogel 14 features a thin, flowable gel, while Echogel 20 is formulated as a medium-thick gel, ensuring versatility for various applications.
Benefits
- Enhanced surface wetting for quick coverage of oily or dirty surfaces
