Echogel

Economical Ultrasonic couplant

Echogel 20 is an economical, medium‑viscosity ultrasonic couplant formulated for inspections where corrosion or salt cake is present. It provides reliable moisture retention, excellent surface wetting, and corrosion inhibition—ideal for flaw detection, sizing, and thickness gauging on salt‑caked or corroded components. It’s silicone‑free and suitable even for hydrogen embrittlement testing environments.

Features

Superior surface wetting for oily or dirty surfaces
Maintains viscosity on corroded or salt‑caked surfaces
Effective corrosion inhibition
Silicone‑free formulation
