Abstract
An ultrasonic transducer is adhered to and electrically and ultrasonically coupled with a surface by means of a room temperature vulcanizing material which is stable when subjected to high temperature and radiation levels. The RTV material is formed from either a vinylmethyl or polyphenyl siloxane matrix containing an iron oxide filler-binder, a cross-linking agent and a finely divided, uniformly dispersed conductive powder. The conductive powder for use in radiation environments is either palladium or graphite and it is homogeneously dispersed by using a temporary dispersing agent.
