Heat Resistant Varnish

Heat-resistant varnishes are a special category of protective coating formulated to withstand and perform effectively under conditions of severe temperature. They are required for components that operate under temperatures at which they experience enormous heat, e.g., in high-speed motors, traction motors, and generators. Jyoti Enterprise manufactures specialty heat resistant varnishes in categories such as epoxy melamine, JYOTI-FR-163 (H-Class Baking Varnish)and they have guaranteed a temperature index between 180-200°C which indicates that the manufacturer has multiple high-performance coatings that can be used in applications with high endurance.

The primary duty of a heat resistant varnish is to sustain its hardness and protective qualities in higher temperature ranges. Unlike conventional varnishes that would deteriorate or lose their effectiveness with exposure to heat, these varnishes form a stable film that will not deteriorate. Jyoti Enterprise's heat resistant varnishes not only have the capability to withstand high heat but also have a variety of other extremely important properties. For instance, their H-class baking varnish is suitable for film formation and is resistant to refrigerants, therefore it is particularly suitable for the stators of hermetic motors. This is to ensure that electrical components are well insulated and safe from thermal breakdown and electrical failure.
