Vaporization of VersaSonic™ vs Sono 600®
The above plot is a technical representation of why VersaSonic (top line) outperforms Sono 600 (bottom line). The plot depicts the weight loss of each couplant due to vaporization over time at 200°C (392°F). Sono 600 loses significantly more mass and vaporizes faster than VersaSonic. Vaporization produces gas bubbles which both attenuate and scatter ultrasound as well as degrades the rheology of the product (coupling doesn’t last as long, dries faster and gets sticky or tacky sooner).
While many Echo customers that have switched to VersaSonic from Sono 600 have observed these characteristic in practice, this test demonstrates the technology behind the experience.
VersaSonic is the ideal high temperature ultrasonic couplant when working under 750°F (400°C). The response is instant as there are no plastic polymers in VersaSonic that need to melt before transmission occurs. At higher temperatures (above 350°F / 177°C) its useful service life is longer than competitive couplants. The auto-ignition temperature for VersaSonic is 788°F (420°C). VersaSonic is available in two viscosities:
- High Viscosity – ideal for spot inspections
- Medium Viscosity – best for spreading

We’ve expanded our line of Echo 8HT fluid UT couplant to include three additional viscosities. Performance of a broad range of AUT and MUT ultrasonic flaw and thickness gaging applications from -50°F to 800°F (-45°C to 425°C) is possible with these four grades, with minimal residue and great signal to noise ratio.
Grade 1 is the lowest viscosity fluid (100 cST) for long or small diameter lines and quick spreading.
Grade 4 is Echo’s standard viscosity fluid (400 cST) and is usually a good compromise between pump ability and run-off at the transducer.
Grade 6 is a higher viscosity fluid (850 cST) that minimizes run-off at the transducer, however, requires system “pump ability” testing.
Grade 10 is a very thick fluid (5,000 cST – honey like) for MUT. It spreads easily over large hot surfaces, stays in place and leaves minimal if any residue.
Introduced in the mid 1970’s by Aerotech / Krautkramer Branson and sold by GE Inspection Technologies for decades, HiTempco has been the standard of performance in silicone based ultrasonic couplants. With a broad temperature range of -50°F to 775°F (-45°C to 412°C), its applications range from high temperature thickness gauging and flaw detection to ambient and low temperature coupling where no corrosion, broad material compatibility, long service life and low toxicity are considerations.
- Very high viscosity
- No residue
- Strong corrosion inhibition
- Non-toxic, non-irritating
- Low environmental impact.
- Contains no perfluorocarbons, peanut or tree nut oils.
-50°F to 775°F (-45°C to 412°C)
Flash Point and Auto-Ignition Temperature
Flash Point: Cleveland Open Cup 250°F
Auto-Ignition Temperature: 820°F
Instantaneous ultrasonic response (does NOT contain plastic powders which delay ultrasonic conduction and result in difficult-to-remove residues). Excellent corrosion inhibitor. Provides non-toxic, long-term corrosion inhibition for steel and cast iron and is compatible with other metals and most plastics. HiTempco may be left in place unless it will interfere with subsequent manufacturing operations such as painting or electroplating.
Removal: wipe with paper or cloth rag. If complete removal is required, dish detergent and water or a chemical degreaser can be used.

Echo Ultrasonics is the first NDT ultrasonic manufacturer to be awarded the new Certified Quality System ISO 9001:2015. Echo develops, formulates and manufactures NDT ultrasonic couplants for the worldwide non-destructive testing industry. Early adoption of the ISO 9001:2015 quality standard demonstrates Echo’s efforts to be leaders in the ultrasonics industry.
Emily Larson-Rutter, Quality Manager of Echo Ultrasonics said, “The new ISO 9001:2015 is a High Level Structure (HLS) which provides a framework for incorporating other quality standards (such as the newly issued AS9100:2016-D). ISO 9001:2015 places additional emphasis on leadership and management commitment being actively engaged and taking accountability for the effectiveness of the company’s Quality Management System. Adherence to ISO 9001:2015 quality standard requires employees to use critical thinking skills focusing on risk.”
As part of the new ISO 9001:2015 certification process, Echo Ultrasonics engaged in a rigorous 3rd party audit of its risk identification and abatement infrastructure, administration and manufacturing processes, as well as customer and product quality requirements. Achieving ISO 9001:2015 certification reflects Echo’s dedication to quality and highlights our structured and systematic approach to the design, development, manufacture and distribution of ultrasonic couplants.

You may be aware that VersaSonic® has superior performance from -10 to 750°F, however, did you know:
- VersaSonic is available in medium viscosity for optimal spread-ability and high viscosity to “stay in place” on a transducer, pipe or overhead surface.
- VersaSonic is available in open-top 1 and 5-gallon pails (5-gallon dispensing pump included at no charge), 1 gallon and quart cubitainers.
- VersaSonic is a versatile broad temperature couplant. The world’s largest producer of power generating equipment has standardized on VersaSonic for use at ambient temperatures due to its compatibility with their electronic components.
- Refineries and heat treatment plants use VersaSonic because its useful service life is up to three times longer than competitive couplants at temperatures above 350°F.
Have a job where you need to spread the couplant in some areas but need it to stay in place in others? Try our quart dual pack of both viscosities.
