Instantaneous ultrasonic response (does not contain plastic powders which delay ultrasonic conduction).

Multiple viscosities covering flaw, corrosion mapping and thickness gaging at high and low temperatures and in mud, snow and rain.

Ambient and low temperature coupling where corrosion inhibition is critical.

Excellent corrosion inhibitor. Provides non-toxic, superior, long-term corrosion inhibition for steel and cast iron and is compatible with other metals and most plastics. VersaSonic may be left in place unless it will interfere with subsequent manufacturing operations such as painting or electroplating.

Low environmental impact. Contains no perfluorocarbons, silicones, peanut or tree nut oils.

Available in two viscosities:

  • HV: High viscosity – remains in place on surfaces and transducers
  • MV: Medium viscosity – spreadable, can be bushed onto surfaces

Removal: wipe with paper or cloth rag. If complete removal is required, dish detergent and water or a chemical degreaser can be used.
