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
