This couplant is designed for use on all types of metallic surface and is especially suited to solving the problems of rough, pitted, uneven surfaces to allow smooth probe movement during testing.
The thixotropic properties of this couplant give excellent wetting and acoustic transmission and do not allow the product to flow all over the test area; and so is very economical to use as you only cover the working area not the whole piece.

Sonagel W incorporates chemicals, which allow very slow drying even at elevated temperatures, whilst being free VOC's and other hazardous materials. However, it does contain a special tracer dye to enable areas to be checked for coverage but the couplant is still easily removed with water or solvent wipes.
Sonagel W is available in easy to use 125ml applicator bottles, 250ml bottles, as well as in plastic 1 litre, 5 litre and 25 litre bulk containers (with suitable carrying handles).
*NB: This product will have a flash point of 160°C (PM) when used for long periods at elevated temperatures.
Couplant V Wallpaper Paste
Couplant is required for sound waves to pass from an Ultrasonic Probe into material under test. Limited and inconsistent couplant application between probe and surface can impact on measurement results significantly. Defect sizing relies on a consistent couplant and known surface attenuation measurements.
Composite Inspection in Phased Array
Nowadays, composite material is being used widely, namely because of its unique characteristics. QA of parts and laminates made of composite is a challenge. Nevertheless, using UT techniques to perform NDT inspection of such parts provides equally reliable and repeatable results for both in-line and maintenance examination.
Spotwelds on automotive components and other structures require inspection for a number of possible failure modes. Adhesive (stick) welds, burnt welds and unfused welds are several types of failure modes.
