Description: Jyoti 151 J is an electric insulating heat curing impregnating varnish based on modified polyester resin.


Areas of Application

In electrical machines, Jyoti 151 J is used both for manufacturing and repairing the following Thermal class H (180) objects:

• Standard motors
• Generators
• Transformers
• Drives in the chemical industry
• Properties of cured material

 The cured material displays very good film formation and resistance to chemicals. The relatively elastic varnish film has good heat resistance. Owing to its temperature index of 180-200 can be used for machines in thermal class H. A reduction in the degree of hardness of enameled wires generally used does  not occur if the components are properly impregnated. Jyoti 151 J contains mild solvents leading to better work environment.

Application Methods

• JYOTI 151 J is processed by all conventional impregnating methods, such as dipping, rolling or flooding. It can also be processed under vacuum. In this case, the vacuum should not drop below 20 mbar to avoid high solvent evaporation. The most advantageous impregnating method in each case depends on the given technical possibilities of the plant, the structure of the components, and the demands placed on the object to be impregnated under operating conditions.
• Jyoti 151 J displays low susceptibility to the influence of foreign substances, such as punching grease, oils or primers, however, contamination of the varnish should be avoided as much as possible. After drainage time of 15-45 minutes at room temperature, the product is cured in the circulating-air oven at the temperatures and periods of time given. For large objects or those with a complicated winding structure a two-stage curing process is recommended to ensure removal of the solvents.
