EchoMix® Powder Couplant | Single-Part Ultrasonic Couplant
The High-Performance, Low-Logistics Solution for Field UT
EchoMix® is a premium, single-part powdered couplant designed to be mixed with water at the job site. Engineered by ECHO Ultrasonics, this powder transforms into a clear, high-viscosity gel that provides exceptional acoustic transmission for flaw detection and thickness gauging. By shipping only the essential chemical components, EchoMix® eliminates the high cost of transporting water, making it the most economical choice for international projects and remote field inspections.
Key Performance Features
Superior Acoustic Impedance: Formulated to provide a strong signal-to-noise ratio, ensuring clear back-wall echoes and precise flaw characterization.
Rapid Mixing Formula: The single-part powder dissolves quickly in water (warm or cold) without the clumping associated with traditional starch-based powders.
Advanced Corrosion Inhibition: Contains a robust inhibitor package that protects both the test specimen and the UT transducer from oxidation and "flash rusting."
Salt & Mineral Tolerance: Maintains its viscosity even when mixed with hard water or in environments with high mineral content, preventing the gel from "breaking" or thinning out.
Environmentally Safe: Non-toxic, non-irritating, and easy to clean up with a damp cloth or water rinse. It contains no oils or silicones that could interfere with post-inspection painting or coating.

Ideal Applications
Remote Pipeline Inspection: Significantly reduces the weight of gear for technicians traveling to remote ROW (Right of Way) locations.
Bridge & Structural Steel: Provides a stable vertical-surface cling for weld inspections on large structures.
Thickness Gauging: Ideal for routine wall-thickness checks on tanks and pressure vessels.
International Export: Drastically lowers shipping and customs fees by removing the weight of liquid water from the shipment.
Mixing Tip: For the best results, add the EchoMix® packet to a 1-gallon container, fill with water, and shake vigorously. Let the mixture sit for 5–10 minutes to allow the polymers to fully hydrate into a smooth, bubble-free gel.
