Sonagel D1 is a stable clear gel specifically designed for ultrasonic inspection and it is non-toxic and safe for the environment. Sonagel D1 is used at a concentration of 50 grams per litre, but a thinner gel can be obtained by reducing the powder content to a minimum of 10 grams per litre.

This product 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.

Sonagel D1 incorporates corrosion inhibitors and wetting agents and is free of VOCs and other hazardous materials. However, it does contain a special tracer to enable areas to be checked for coverage but the couplant is still easily removed with water or solvent wipes.

NB: This product is designed for use ‘on site’ for specific spot tests, where it is impractical to carry or deliver (ready to use) bulk couplant. (Sonagel O, Sonagel W)

Sonagel D1 is available in 1-kilo plastic tubs.

Water based W, oil based Sonagel O and high temperature Sonagel HT are also available as standard. Other couplant's may also be supplied upon request.
