Abstract
A composition is disclosed of a metal dithiocarbamate, a resinous carrier, and a solvent. The composition is applied to a portion of an electrical apparatus which is exposed to a gas stream. The solvent in the composition is evaporated to produce a thermoparticulating coating. When the electrical apparatus overheats the metal dithiocarbamate in the coating forms particles in the gas stream which are detected by the monitor.
Claims20
A method of protecting electrical apparatus from damage to overheating and for thereafter determining the locating of said overheating, said apparatus including a gas stream and a monitor for detecting particles in said gas stream and for emitting a signal when said particles are detected comprising:
- A. preparing a composition according to claim 1;
- B. applying said composition to said electrical apparatus at positions exposed to said gas stream;
- C. evaporating the solvent in said solution;
- and
- D. monitoring said gas stream for the presence of particles therein.
A thermoparticulating coating comprising a solid layer of a cured resinous carrier containing a metal dithiocarbamate.
A composition comprising at least one metal dithiocarbamate and a solution of a resinous carrier curable and stable at 60.degree. C, and unreactive with said metal dithiocarbamate.
