Features

    JS-812 insulating varnish has unique self-drying properties, high heat resistance, adhesion, moisture resistance, enthalpy and insulation. Chemical resistant Corrosion and other properties, is a Class B insulation material suitable for submerged immersion motor electrical appliances, transformer coil set for moisture insulation.

Body composition:

    Synthetic resin, organic solvent, additives, additives.

Drying time:

    Dry for 15 minutes and dry for 6-12 hours.

Heat resistance:

    (130 ° C ± 2 ° C, 30 micron paint thickness) baked for 30 hours without bending through 3 mm bending.

Oil resistance:

  (immersed in the No. 10 transformer for 24 hours) through the experiment)

Breakdown strength:

    Normal state ≥ 70 kV / mm, water immersion ≥ 40 kV / mm

Volume resistivity:

    Normal state ≥ 1 x 103 ohms. Cm, water ≥ 1X1012 ohm.cm.

Instructions:

    (1): impregnation side washing vacuum impregnation, pressure impregnation, submerged impregnation and casting impregnation, especially under vacuum pressure impregnation.

    (2): After immersion, it is placed in a ventilated, dust-free, drip-dried, and then dried in an oven. The drying temperature and time are determined by the size of the armature.

    (3): Dilution method: use the JS-400 of the company to adjust the viscosity, the ratio is determined according to the process requirements of the workpiece size, mixed by 1:1Lkgrj

         The combination is between 0.88 and 0.90 (the mixture should be measured between 14 and 18 seconds with a 4# viscometer). It is recommended to test once every two hours.

Packing: 20L iron can or 200L iron drum
