ABSTRACT:
A composition is disclosed of a solution of a resinous carrier and at least two compounds which thermoparticulate at different temperatures between 60.degree. and 200.degree. C. A coating is made by applying the composition to a portion of an electrical apparatus exposed to a gas stream. As the temperature of the coating increases the compounds therein thermoparticulate. The time between which the compounds thermoparticulate indicates the rate of rise of the temperature and analysis of the products of thermoparticulation indicates the location of the coating in the electrical apparatus. Alternatively, the coating can consist of several layers with a thermoparticulating compound in each layer which thermoparticulates at different temperatures.
