Echo 3HT Fluid
When water won’t work, Echo 3 HT is the next step. For temperatures up to 350°F (177°C), Echo 3 HT is water soluble, leaves no residue and is compatible with a broad range of materials.
Key Benefits :
- Water-soluble
- No need to remove
- Least expensive intermediate temperature fluid
- Broad operating range -30 °F to 350°F (-34°C to 177°C).
- Water soluble: easier to remove than most fluid ultrasonic couplants.
- No “oil slick” when used where couplant may drip into a body of water.
- Lowest viscosity fluid that remains pumpable down to 35°F / 2°C.
- Low toxicity.
- Compatible with a broad range of materials including most metals, plastics and composites.
- Good Surface wetting due to low surface tension and solvent properties.
- Slow Drying at ambient temperatures.
- Contains no glycerin which can interfere with subsequent penetrant inspection.
- Environment and operator friendly – no formaldehydes, nitrates, nitrites or glycol ethers.
- Minimal residue
- Removal: Wipe with wet or dry paper or cloth rag or water wash.
