What are the characteristics and application characteristics of insulating coatings

       The insulating coating must have the effect of blocking current flow through the insulator. The general characteristics and application characteristics are as follows;

(1) The dielectric strength of the coating is measured under specific temperature and temperature conditions, and as the temperature increases, the dielectric strength decreases;

(2) In order to improve the dielectric strength and reduce the influence of temperature on it, the oxide ceramics can be treated with mechanical sealants;

(3) The resistance coating is applied to the insulation of the heater pipe and the welding head of the soldering iron.

The resistance coating often uses AI2O3 ultrafine powder and 87%AI2O3+13%TiO2 composite powder.
