1. A sonotrode, comprising:
a first end adapted to be connected to a mechanical vibrations source,
a working tip for spraying a hot material at an opposite end of the sonotrode, and
a body with a cooling jacket, sealed with a first seal and a second seal,
wherein the first seal is placed in a proximity of a location of the node of the standing wave excited in the sonotrode in its working condition,
wherein the second seal is at a place of contact with the body of the sonotrode place near the antinode of a standing wave in the body of the sonotrode closer to the working tip than the first seal,
wherein the second seal is equipped with a resilient element and a shield for protecting resilient element from the hot sprayed material, and
wherein the resilient element is an elastomer.
