Abstract
A composition is disclosed of a sulfonic acid or amine salt thereof, 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 sulfonic acid or amine sulfonate in the coating forms particles in the gas stream which are detected by a monitor.
