The Sonagel range is designed for use on all types of metallic surface and is especially suited to solving the problems of rough, pitted, uneven surfaces allowing 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. This makes it very economical to use as you only cover the working area and not the whole piece, and is especially suitable for vertical and overhead surfaces.
Sonagel incorporates chemicals, which allow very slow drying even at elevated temperatures, whilst being free of 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 very easily removed with gentle water washing or solvent wipes.

Sonagel O is a stable pink/orange couplant gel intended for use as a replacement for mineral oils and greases, within NDT environment. Hydrocarbon based,
Sonagel O retains a gel state without causing corrosion or drying on the test surface. The gel has a flash point of 175° (PM) and operates within the temperature range of -10°C - 75°C.
Sonagel O is available in easy to use 125ml applicator bottles as well as in plastic 1 litre, 5 litre and 25 litre bulk containers (with suitable carrying handles).
Sonagel D1 is a bright yellow fine powder that when mixed with water, forms a stable clear yellow gel specifically designed for ultrasonic inspection. 1 kilo of D1 powder makes 20 litres of couplant when mixed with water. This product is specifically designed for 'on site' spot tests where it is impractical to carry or deliver ready to use couplant in bulk.
Sonagel W is a stable clear yellow couplant gel specifically designed for ultrasonic inspection. It is non-toxic and safe for the environment.
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.
Sonagel LTHT is a thick translucent couplant paste specifically designed for ultrasonic inspection at temperatures up to 250°C and is non-toxic and safe for the environment.
Sonagel LTHT is easily removed with solvents such as Alcohol, Acetone or Hydrocarbon distillates.
Hazardous decomposition does not occur at elevated temperatures, the product will start to liquify as temperatures increase up to 300°C.
Sonagel LTHT is available in easy to use 1 litre plastic container.
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.
