Abstract
A bonding material is disclosed which is stable at high temperature and radiation levels, which may be conductive and which is particularly suited as a couplant to ultrasonically and electrically couple an ultrasonic or acoustic transducer to a surface. The material comprises a carborane polysiloxane adhesive, a vehicle-solvent which will evaporate such that the bonding material cures by vehicle-solvent release, and a wetting agent. The material may also contain conductive materials which are suitable for the conditions of intended use and may also be enriched in B.sup.11 to avoid the adverse effects of B.sup.10 when subjected to radiation.
Claims8
A method of adhering and acoustically and electrically coupling an acoustic transducer to a surface wherein said coupling will be subject to high temperature and radiation comprising the steps of applying a layer of electrically conductive coupling material between said transducer and said surface and allowing said coupling material to cure by vehicle-solvent release to cause said transducer to be adhered and coupled to said surface, said coupling material comprising:
- a. a carborane polysiloxane adhesive;
- b. a vehicle-solvent for said carborane polysiloxane adhesive, said vehicle-solvent being evaporatable from said bonding material whereby said bonding material will cure by vehicle-solvent release;
- c. a wetting agent;
- and
- d. a conductive agent.
