Product Features

Safe and environmentally friendly, non-flammable and non-explosive;

Excellent insulation properties, non-softening or sticky even under thermal conditions, stable electrical resistance, and superior inter-turn reinforcement; moisture-resistant and rust-proof; strong bonding strength, ensuring secure yet flexible fixation of both upper and lower winding ends; bright, uniform, and high-quality varnish coating on the surface of silicon steel sheets; available in heat resistance classes F and H.

Product applications:

Range hoods, air conditioners, fan motors, universal motors, and reactors.

Three-phase induction, water pump motor, external rotor fan, generator rotor.

Automotive and motorcycle starter motor stator and rotor impregnated with insulation.

Storage:

After mixing with water, it should be stored in a cool, well-ventilated area. The recommended storage temperature for the bath solution is below 30°C, and the paint tank must be covered for protection.

Add fresh liquid at least once every 5 days, and mix thoroughly before use.

Storage is recommended for up to 3 months at temperatures below 30°C. If stored beyond this period, the liquid can still be used normally as long as it passes inspection and remains uniformly shakeable.

Construction process:

Paint Mixing:

Paint: Mix with water at a ratio of 1:0 to 1 (for micro-motors with stator wire diameters ≤0.10 mm, water can be added up to a 1:1 ratio based on the required paint volume; for other motors, the paint can be used directly without dilution). The recommended application viscosity is 10–13 seconds (using a No. 4 viscosity cup). If the viscosity exceeds the upper limit of the recommended range, adjust it by adding tap water.

Continuous Immersion:

Stator preheating (3 stations) – cooling (2 stations) – varnish impregnation (1 station) – drip coating (3 stations) – baking. Each station represents one beat, with the beat time determined by the drying duration.

Vacuum Immersion:

Immersion/dipping can be performed either at atmospheric pressure or under vacuum. The dipping time should be 3 to 25 minutes—or until the stator is fully saturated, plump, and free of visible air bubbles.

Drain after dipping in varnish:

When performing manual dip-coating or hanging-dip operations, allow 10–30 minutes for draining—or until no obvious paint dripping remains—before transferring the parts into the oven for baking. For vacuum impregnation or continuous immersion processes, directly feed the parts into the curing oven or drying tunnel according to the immersion machine's cycle time (typically 3–5 minutes per cycle) for heat preservation and drying.

Baking and curing time:
1. Automotive and motorcycle parts, power tools, and series-wound stators: Bake at 110°C for 100 minutes or at 135°C for 80 minutes.
2. Stator for hoists and fans: Insulate and bake at 115°C for 90 minutes, or at 145°C for 45 minutes.
3. Three-phase induction, water pumps, smoke extractors, air conditioners, and fan motors: Insulate and bake at 125°C for 2 hours. (The specific baking time should be determined through testing, taking into account the motor size and the equipment’s ventilation conditions, to identify the optimal curing conditions and baking duration.)
