Powder Ultrasonic Couplant
EchoMix Single Powder Ultrasonic Couplant

EchoMix Single is a one-part (one packet) powder, easily mixed in ambient water in five minutes, providing a strong, continuous coupling film that adheres well to vertical and overhead surfaces. Single mix packet, one-step mixing.
Operating Range | 32˚ to 120˚F (0˚ to 50˚C) |
Viscosity | Medium Gel |
Halogens and Sulfur | Less than 0.02% (200 ppm) |
pH | 9 |
Corrosion Characteristic | Contains mild short term Ferrous Corrosion Inhibitors |
Compliance: ASME Boiler & Pressure Vessel Code (T-533), FAA-AC # 25-29 (glycerin-free), NAVSHIPS 250-1500
- Easiest mixing powder couplant
- One packet
- Less residue
- Blue mixing tracer
- Salt stable – will not thin with corrosion salts or in marine or highway environments.
- Fast, easy removal with water
- Low toxicity and low environmental impact
- Compact for shipping and storage
- Easy mixing, fast gel time in ambient water
- Working with EchoMix Single:
- Removal: Remove with a dry rag, water and brush or pressure washer.
- Air Bubbles: All powder couplants will form small air bubbles after mixing if water is not de-aired. These small bubbles usually do not negatively affect the use of the couplant and will dissipate in 3-4 days. If an air bubble-free couplant is desired immediately, use hot water and stand overnight; then add the powder couplant.
- The Blue Color is a visual marker to ensure uniform distribution of the corrosion inhibitor by encouraging thorough mixing.

Working with EchoMix
To lower the freezing point to -26 F (-32 C), raise the operating temperature to 250 F and extend drying time:
- Mix the large “A” packet into two quarts of water as directed.
- DISCARD the small packet “B” and replace it with two quarts of propylene glycol formula antifreeze, following the same directions for the “B” packet. (“B” packet is not used when adding antifreeze) The couplant will thicken within 60 seconds; therefore, add the anti-freeze smoothly and mix completely within the 60-second window.
- Appropriate propylene glycol anti-freezes include Sierra Antifreeze coolant, Amsoil Propylene Glycol Antifreeze, Prestone Low Tox and are designated as less toxic to animals and pets.
- Do not use ethylene glycol antifreeze or methyl alcohol. These chemicals are toxic to the environment, dangerous to animals and will not work with EchoMix.
- When using propylene glycol antifreeze, the viscosity of prepared EchoMix will be higher than when mixed with 100% water. Therefore, use ½ packet for medium viscosity and 2/3 packet for high viscosity gel.
