Hamikleer® 712 and 712-2 are water soluble synthetic couplants for ultrasonic testing replacing glycerine. The buffering action of this Hamikleer® 712 series permits testing of many metals and metallic couples that typically corrode in aqueous-phase couplants. The low halogen content makes the Hamikleer® 712 series the ideal material to use on titanium and other space-age metals, where possible halogen stress corrosion could be a problem. The exceptional water solubility and solution clarity of the Hamikleer® 712 series allows easier rigging and positioning in submerged tank testing. There are several viscosity grades for this product, contact us for a version formulated to meet your specific needs.
