HiTempco Couplant

HiTempco Couplant

Echo Ultrasonics

With a broad temperature range of -50˚ to 775˚F (-45˚ to 412˚C), its applications range from high temperature thickness gaging 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
  • Non-drying
  • Strong corrosion inhibition
  • Non-toxic, non-irritating
  • Low environmental impact. Contains no perfluorocarbons, peanut or tree nut oils

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.
