Usage

1. Mix two components A/B with a proportion of 1/1 by weight uniformly,

2.Automatic trickle varnishing machine process:

2.1 Preheating at 120-145°C for 15-20 minutes.

2.2 Drip slowly.

2.3 Gelling at 105-120°C for about 12 minutes.

2.4 Curing at 135-145°C for 30-40 minutes.

3. Manual trickle varnishing machine process:

3.1 Preheating at 120°C for 1 hour.

3.2 Clamp the hot rotor on the machine and warm it, paint by brush or metering pump until the resin is full, rotate until get gel.

3.3 Curing at 120-130°C for 2-3 hours.

4. Stator immersion process:

4.1 Adjust the viscosity at 11-13s/23°C by adding 80-150% 202-X thinner.

4.2 Preheat the stator coil, and then immerse in the resin.

4.3 After drip-dry, bake the unit at 120-130°C for 2-3h for fast-drying immersion, at 130°C for 40-80 minutes for continuous immersion.
