- Customizable: Hardness, viscosity and operating time can be adjusted as needed
Product Features & Advantages
- Excellent Flame Retardancy: Forms a reliable flame-retardant system, effectively preventing fire risks caused by controller short circuits, complying with global safety standards for electric vehicles.
- Low Shrinkage & Non-Corrosive: No exotherm or corrosion during curing, avoiding damage to controller chips, soldered joints and PCB substrates, ensuring component integrity.
- Superior Waterproof & Insulation: High sealing performance, preventing moisture, dust and water penetration, ensuring safe operation of controller circuits in various environments.
- Shock & Vibration Resistance: Maintains elasticity in a wide temperature range, absorbing impact and vibration from scooter operation, protecting controllers from road bumps and falls.
- Easy to Use: 1:1 weight mixing ratio, simple operation, supports room temperature or heated curing, adapting to mass production of electric scooters.
- Durable & Stable: Resists chemical media, yellowing and weather aging, ensuring long service life of controllers, reducing after-sales costs.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Fully stir Component A and Component B separately in their respective containers to ensure uniform consistency and avoid sedimentation.
- Component Mixing: Mix Component A and Component B strictly at a 1:1 weight ratio, stirring continuously until homogeneous.
- Vacuum Defoaming: Place the mixed compound in a vacuum container and defoam at 0.08MPa for 3 minutes to remove air bubbles.
- Curing Process: Pour the mixture into electric scooter controller housings; cure at room temperature or heat to accelerate (80℃ for 4-5 hours). Adjust curing speed according to ambient temperature.

FAQ
Q: Is this potting compound suitable for mass production of electric scooter controllers?
A: Yes. It features a simple 1:1 mixing ratio, easy operation and adjustable curing speed, perfectly adapting to the mass production needs of electric scooter controllers.
Q: What substances should be avoided during use to prevent curing failure?
A: Avoid contact with organotin compounds, sulfur and sulfides, amine compounds, incompletely cured condensation silicone, amine-cured epoxy resin and solder flux, which will affect curing.
Q: How to store unused potting compound?
A: Seal Component A and B separately, store at below 25℃ (shelf life: 1 year). Use mixed compound at one time; stir well if layering occurs, which does not affect performance.
Q: Can it be customized for high-power electric scooter controllers?
A: Yes. We can optimize thermal conductivity and flame-retardant performance to meet the high-temperature and high-power operation requirements of electric scooter controllers.
