Forever Wedge Couplant is a high viscosity fluid for phased array and angle beam attachment and for coupling delay lines. It won't dry, run, leach or dissolve with water or couplants. If applied properly, it can stay in place until you decide to remove the wedge. Forever Wedge Couplant is thermally stable and will separate with temperature change. It is not an adhesive and will not bond to the wedge and it often lasts for the life of the probe or wedge without hardening or evaporating and yet is easily removed.
Forever Wedge Couplant eliminates the need to replace wedge couplant during inspections and prevents the unintentional change of test parameters due to partial wedge-to-transducer failure. It eliminates element drop out from failed wedge to transducer coupling and is impervious to water, heat, light and is non-toxic.
