About the Couplant U 51
U 51 is a water-based white laminating gel. It is suitable for the most common applications under normal conditions of use for both defect and thickness checks. The presence of anti-corrosives prevents oxidation, so it is not essential to remove the gel after the check. The product is non-toxic to the skin, has no hazard labels and is not harmful to the environment. Intended NDT method: ultrasonic testing. CGM states compliance with ASME V Art.5 (T-533), FAA AC 25-29 (glycerin free), MIL-STD-271, PMUC (certificate of compliance upon request). Published packaging: 5 kg buckets.
- Excellent coupling agent, suitable for different types of surfaces
