Chemetall UCA-2M 

Water-Soluble Ultrasonic Couplant 

UCA-2M is a water-based bright blue transparent gel, consisting of a blend of coupling agents, organic corrosion inhibitors and thickening agents.

UCA-2M has marked thixotropic properties which ensure it stays in position when applied and does not drip or run from the part under test. The thixotropic and excellent wetting properties ensure free and even movement of ultrasonic probes over both rough and smooth surfaces with immediate and excellent acoustic transmission.

UCA-2M is neutral in reaction (pH value 7.5 - 8.5) and the presence of special organic corrosion inhibitors ensures that it will not corrode most metals. The product is low in sulphur and halogens and essentially ash free on ignition.

Applications

UCA-2M is normally applied by hand or with a soft bristle brush. It is completely soluble in water and can be readily removed by washing with water. Where the use of water is not convenient or practical, UCA-2M can be removed with alcohol, acetone or similar solvent.

UCA-2M is normally used as supplied but can be pre-diluted with water. When diluted with an equal quantity of water, UCA-2M retains its thixotropic properties. More dilute solutions retain enhanced viscosity and powerful wetting properties.

UCA-2M contains-freezing point depressants. Working temperature range: - 10 °C to +50 °C. Above 50 °C, some evaporation of water will take place on prolonged exposure.

Effects on materials

UCA-2M contains no powerful solvents and is therefore without effect on painted surfaces, plastics, synthetic or natural rubbers
