- Signal Compatibility: High insulation without interfering with wireless signal transmission, ensuring stable, efficient charging performance.
- Strong Adhesion: Excellent bonding to PC, ABS, PVC, metals and PCB boards, ensuring tight encapsulation and no component detachment.
- Flame-Retardant & Safe: UL94-V1 flame-retardant rating, fully complying with EU RoHS standards, eliminating fire risks and ensuring user safety.
- Waterproof & Dust-Proof: High sealing performance, protecting internal components from moisture and dust, adapting to daily use environments.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Fully stir Component A to evenly mix settled fillers, and shake Component B thoroughly before use to ensure uniform viscosity and performance.
- 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 wireless charging pad housings; cure at room temperature. Basic curing takes 3-5 hours, full curing takes 12-24 hours (ambient temperature/humidity affects speed).
