SOUNDSAFE®
is recommended for
applications where ultrasonic couplant may not be removed by the inspector and
may later come into contact with animals, humans and waterways. It offers the
highest performance of the environmentally benign family of couplants. SOUNDSAFE,
a gel couplant, has a high humectant level, including glycerine, to slow drying
and provide transducer lubrication. SOUNDSAFE contains an environmentally benign
corrosion inhibition system for steel; however, when ferrous corrosion is of
primary concern, ULTRAGEL
II® provides superior corrosion inhibition. SOUNDSAFE holds on overhead surfaces and fills
depressions in rough surfaces, facilitating its use in flaw detection, thickness
gaging, and acoustic emission testing.
SOUNDSAFE
meets the Halogens and Sulfur requirements specified in NAVSHIPS MIL-STD-767.
