  • Patent number: 4738737
    Abstract: A couplant material for establishing a sound path of good acoustical impedance between a transducer and a supporting wave-transmitting substrate which is capable of being easily shaped at room temperature, withstanding thermal cycling from room temperature to over 450.degree. F., and substantially maintaining its acoustical properties in a radiation atmosphere while providing a minimum of irritating fumes and outgassing. The couplant material is a non-flammable, grease-like silicone fluid heavily filled with zinc oxide. It has been used previously as a heat sink compound for electronic components.
