Low To Intermediate Temperature Couplant

SuperSonix

The best water-based high-performance couplant with a broad operating range and slow evaporation rate.

Looking for a slower evaporation rate, try EchoPure.

Operating Range -10° to 220°F (-23° to 104°C)
Viscosity Medium flowable gel
Halogens and Sulfur Less than 50 ppm
pH 8.0 nominal at 20°C

Compliance: ASME Boiler & Pressure Vessel Code (T-533), ASTM F519, NAVSHIPS 250-1500,Nuclear grade (less than 50 ppm Halogens & Sulfur)

EchoPure

EchoPure is the couplant of choice for Phased Array UT Inspection (PAUT). EchoPure improves defect reproducibility by eliminating dry spots under the wedge and the resulting noise and artifacts.

The most universal water-soluble | water-free UT couplant and the couplant of choice for Phased Array Manual UT inspection. Very Slow drying and ideal for cold and elevated temperature inspections.

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.

Operating Range -60°F to 350°F (-51°C to 176°C)
Viscosity Low- fluid
Medium -fluid
High-stiff gel like fluid
Auto Ignition Temperature 700°F / 371°C
Corrosion Characteristics Meets ASTM F519
Very good
Halogens and Sulfur Less than 50 ppm

Compliance: ASTM F519, FAA-AC # 25-29 (glycerin-free), NAVSHIPS 250-1500, Nuclear grade (less than 50 ppm Halogens & Sulfur), P91 Steel Inspection – meets requirement for a water-free couplant, SME Boiler & Pressure Vessel Code (T-533)

Ultrasonix

Meets FAA Advisory Circular AC 25-29 which states: Procedures need to ensure glycerin is not used on aluminum materials, as it may cause corrosion.

UltraSoniX is a high-performance couplant, available in two viscosities: High viscosity couplant remains in place on vertical and overhead surfaces. Medium viscosity for spreading.

No glycerin is required for carbon fibre composites.

Operating Range 10°F to 220°F (-12°C to 104.4°C)
Viscosity Medium (standard) ~60,000 cps, flowable gel
High ~ 165,000 cps, stiff gel
Halogens and Sulfur Less than 50 ppm
pH 8.0 nominal at 20°C

Compliance: ASME Boiler & Pressure Vessel Code (T-533), ASTM F519, Conforms to FAA Circular Advisory AC No: 25-29, NAVSHIPS 250 – 1500, Nuclear grade (less than 50 ppm Halogens & Sulfur)

Viscosity Standard (medium: flowable gel)
High (stiff gel, stays in place)
Halogens and Sulfur Less than 50 ppm
pH 8.0 nominal at 20°C

Compliance: ASME Boiler & Pressure Vessel Code (T-533), FAA AC #25-29 (Glycerin-free), NAVSHIPS 250-1500, Nuclear grade (less than 50 ppm Halogen & Sulfur)

SoniX

Slow drying for an extended inspection time.

Completely salt stable; will not thin with corrosion, marine environment, or highway infrastructure subjected to de-icing salts.

The best choice for a low cost general purpose ultrasonic couplant with a strong film strength that is slow drying.

Good ferrous corrosion inhibition; compatible with most metals, plastics, and composites.

Safety: environmentally benign.

Environment and operator-friendly – no formaldehyde, nitrates, or nitrites.

 

Operating Range 18°F to 120°F (-8°C to 50°C) for most flaw detection and thickness gaging applications.
