How to Use (Step-by-Step)
- Pre-Mix Preparation: Fully stir Component A to evenly mix settled fillers, and shake Component B thoroughly to ensure uniform viscosity and performance (critical for waterproof effect).
- Component Mixing: Mix Component A and Component B strictly according to the specified weight ratio, stirring continuously until homogeneous.
- Vacuum Defoaming: Place the mixed compound in a vacuum container and defoam at 0.01MPa for 3 minutes to remove air bubbles, then proceed to potting.
- Curing Process: Pour the mixture into underwater LED lighting housings; cure at room temperature or heat. Proceed to the next process after basic curing, and ensure full curing (24 hours) for optimal waterproof and protection effect.

FAQ
Q: Is this potting silicone suitable for seawater underwater LED lighting?
A: Yes. It has strong corrosion resistance, effectively resisting seawater erosion, ensuring stable operation of underwater LED lighting in marine environments for a long time.
Q: What to do if the silicone layers after storage?
A: Stir Component A and B evenly separately before use; layering does not affect product performance, ensuring normal curing and waterproof effect.
Q: Can it be customized for deep-water underwater LED lighting?
A: Yes. We can optimize waterproof performance and adhesion to adapt to deep-water pressure, ensuring tight encapsulation and no water intrusion.
Q: Which curing type is better for underwater LED lighting production?
A: Addition-curing type is recommended for mass production, as it has faster curing speed and better waterproof performance; condensation-curing type is more cost-effective for general underwater LED lighting.
