EchoPure is the couplant of choice for Phased Array UT Inspection (PAUT). EchoPure improves defect reproducibility by eliminates dry spots under the wedge and the resulting noise and artifacts.
EchoPure complies with P91 steel inspection requirement for a water-free couplant.
EchoPure is an ideal couplant for very cold inspection (liquid gas piping and refrigerant lines) and will not frost or attenuate at temperatures as low as -60°F.
EchoPure is excellent for high temperature use such as warm welds up to 350°F and on pipe in the desert summer sun, where slow evaporation and long inspection windows are desired.
With its low toxicity, EchoPure is a good choice for inspection in food processing plants.
EchoPure is the safest commercial NDT ultrasonic couplant. EchoPure is manufactured using only ingredients that are Generally Recognized as Safe (GRAS) as food additives by the US FDA.
EchoPure is a water-free, water-soluble ultrasonic couplant that has a broad operating range, is slow drying and provides excellent transducer lubrication. It is low toxicity and environmentally friendly.
Operating range: -60 to 350°F (-51 to 177°C)
Four viscosities: fluid, low, medium and high
Strongest coupling film available.
Very slow drying: Drying time is days or weeks.
Salt stable. Does not thin with corrosion, roadway or marine salts.
Better multi-metal compatibility than most UT couplants.
Does not contain Glycerin
Environment and operator friendly: no formaldehydes, phosphates, silicones, fragrances, nitrates, nitrites, heavy metals, azoles, antimicrobials or fungicides
Safe: all ingredients are approved for incidental food contact
