CF-4H High-Temperature Coupling Fluid

Advanced Solution for Demanding Ultrasonic Applications

The CF-4H Coupling Fluid is formulated for reliable ultrasonic testing and thickness measurement across an exceptionally wide temperature range. Designed for industrial environments where extreme heat is present, CF-4H ensures efficient transmission of ultrasonic energy between the transducer and the test surface. This biodegradable, high-viscosity couplant provides long-lasting performance and superior corrosion protection under the most demanding conditions.

Key Features

• Wide temperature range: Operates effectively from 0 °F to 600 °F (-18 °C to 316 °C), suitable for high-temperature inspections in power generation, petrochemical and aerospace industries.
• Excellent corrosion protection: Provides outstanding corrosion inhibition, extending the service life of both the couplant and ultrasonic equipment.
• Very slow drying: Ideal for prolonged inspections or long-term coupling where reapplication is impractical.

Key Benefits

• Versatile performance: Suitable for flaw detection, thickness measurement and acoustic emission testing in high-temperature environments.
• Easy application: The high-viscosity formula allows smooth, bubble-free application and stable acoustic coupling.
• Broad compatibility: Works effectively with most ultrasonic transducers and measurement systems.
