Normal incidence shear wave transducers require a stiff, high viscosity couplant to support shear waves. Echo Shear Wave ultrasonic couplant transmits normal incidence (zero degree) shear waves, is nontoxic, water-soluble and easily applied and removed.
size: 2 fluid oz. / 59ml tube
A small amount of Echo Shear Wave Couplant should be placed on the face of the transducer or the test piece and then pressed into a thin layer. For optimum coupling, it is important that the couplant layer be thin.
Echo Shear Wave Couplant is water soluble and easily removed with wet or dry wiping or water wash.
Low Toxicity: Non-irritating, non-toxic. Contains no VOCs, naptha, oil, hydrocarbons, glycerin, glycols, silicones, petroleum distillates, dyes or fragrance.
Operating Range: 40˚ to 90˚F (4˚ to 32˚C)
Viscosity: High viscosity paste
