JYOTI 141 FD (“H-Class” Air Drying Varnish)

Jyoti – 141 – FD processed by all conventional Air Drying methods, such as dipping, rolling or looding. 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 Air Drying 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 Insulating Varnish Air Drying, Air Drying under operating conditions. 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 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.

Description : JYOTI 141 FD (“H-CLASS” AIR DRYING VARNISH)

Jyoti – 141 – FD an electric insulating Air Drying varnish based on modified polyester resin.

Areas of Application

In electrical machines, Jyoti-141-FD used both for manufacturing and repairing the following Thermal class H (195) objects:

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 enamelled wires generally used does not occur if the components are properly Air Drying. Jyoti-141-FD contains mild solvents leading to better work environment.
