HiTempco Ultrasonic Couplant

Introduced in the mid 1970’s by Aerotech/Krautkramer Branson, HiTempco has been the standard of performance in silicone based high temperature couplants for decades.

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

Operating Range: -50˚ to 775˚F (-45˚ to 412˚C)

Viscosity: ≈40,000 cps. Brookfield

Flash Point: Cleveland Open Cup 649˚F (343˚C)

Auto-ignition: 820˚F (437˚C)

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.
