Coupling paste

More information

Ultrasonic probes are coupled to the surface of the test object via special coupling means. Through the coupling means, an air gap is prevented from forming between the test head and the test object, which would cause the would hinder sound from entering the test object.

Coupling pastes developed by HELLING are water washable. The content of sulfur and halogens is below 50 ppm. They contain corrosion inhibitors and bactericides.

The coupling pastes are available in different colours and for different temperature ranges.

Larger delivery quantities are also available on request.
