HiTempco has a very high viscosity.
With a broad temperature range of -50° to 775°F (-45° 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.
HiTempco has an Instantaneous ultrasonic response - does not contain plastic powders which delay ultrasonic conduction and result in difficult-to-remove residues. Excellent low-term corrosion inhibition providing 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. Low environmental impact. Contains no perfluorocarbons, peanut or tree nut oils.
