DRD9660-12002 Water-Based Insulating Coating, Motor Insulation Paint, Transformer Insulation Paint – Waterproof
Product features:
Safe and environmentally friendly, non-flammable and non-explosive;
Excellent insulation properties; water-resistant and moisture-proof, with superior salt-spray resistance; outstanding electrical performance—winding is tightly secured, and wires remain firmly in place without loosening; the silicone steel sheet surfaces feature a bright, uniform coating; thermal resistance rating ranges from Class F to Class H.
Product Introduction:
Appearance: Milky white liquid
Odor: Low odor; no off-putting smells during baking
pH: 6.5–9.5
Viscosity: 10–15 s / 25°C
Usage:
Various fractional-horsepower motors, universal motors, and fan/ventilator motors;
Three-phase induction motors, new-energy vehicle motors, and servo motors.
Robots, drone motors, transformers, and reactors.
Storage:
Store in a cool, well-ventilated, and dry place. The recommended storage temperature is 15–35°C. Keep the packaging tightly sealed and store away from any ignition sources.
Do not mix with products from different systems;
The shelf life is 3 months at temperatures below 35℃. If stored beyond this period, the product can still be safely used after passing a quality check confirming the liquid remains uniformly homogeneous.
Construction process:
Paint Preparation: Mix this paint with water at a ratio of 1:1, stir thoroughly, and then directly immerse the stator. The recommended application viscosity is around 10–11 seconds (using a No. 4 viscometer). If the viscosity exceeds the upper limit for application, dilute further with clean tap water (tap water must meet drinking standards).
Preheating: (Hand-dipping varnish does not require preheating the stator)
The workpiece should be preheated at approximately 120°C for 10 minutes, or until it is fully heated. Once the stator has cooled down to 50–60°C, it can then be immersed in the paint bath.
Paint liquid circulation: When the stator is preheated, after continuously immersing the preheated stator, the paint liquid must be circulated or cooled to prevent the oil tank's paint temperature from exceeding 35°C.
Immersion: Immerse at atmospheric pressure for about 3–5 minutes, or until the stator is fully saturated, plump, and free of visible air bubbles.
Draining (air-drying): For manual dip-coating or hanging-dip operations, allow the parts to drip dry for 5–30 minutes—or until no noticeable paint dripping remains—before transferring them to the oven for baking. In contrast, for vacuum impregnation or continuous immersion processes, directly feed the parts into the tunnel oven according to the immersion machine’s cycle (typically 3–5 minutes per cycle), where they are then dried at high temperatures.
Baking and Curing: Bake in a curing oven at 120°C for 1.5–2 hours or longer. (The specific baking time should be determined through testing, taking into account the size of the workpiece, equipment conditions, and the desired level of paint curing, to identify the optimal curing conditions and baking duration.)
