Product Features & Advantages
- Aerospace-Grade Flame Retardancy: Forms a reliable flame-retardant system, meeting strict aerospace safety standards to protect flight recorders from fire damage and preserve critical data.
- Zero Exothermic & Low Shrinkage: Cures without releasing heat, avoiding thermal damage to delicate electronics; minimal shrinkage ensures precise encapsulation and structural stability.
- Dual Curing Modes: Supports room-temperature or heated curing, flexible to adapt to aerospace manufacturing workflows; winter low temperatures can be adjusted with heating to accelerate curing.
- Superior Multi-Protection: Excellent waterproof, moisture-proof, mold-proof and dust-proof performance; resistant to chemical media, yellowing and weather aging, adapting to extreme aerospace environments.
- High Insulation Performance: High dielectric strength and volume resistance effectively isolate electrical components, preventing short circuits and ensuring stable operation of flight recorders.
- Non-Corrosive & Easy to Use: No corrosion to electronic components; simple 1:1 mixing ratio, easy to operate, suitable for mass production and precision encapsulation.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Thoroughly stir Component A and Component B in their respective containers to ensure uniform texture, as slight stratification may occur during storage (stratification does not affect performance).
- 1:1 Weight Mixing: Strictly mix Component A and Component B at a 1:1 weight ratio, stirring continuously until homogeneous to ensure optimal curing effect.
- Vacuum Defoaming: After mixing evenly, place the silicone in a vacuum container and defoam at 0.08MPa for 3 minutes to remove air bubbles, ensuring dense encapsulation.
- Curing Process: Pour the defoamed silicone into flight recorder components. Curing effect is temperature-sensitive; it can be cured at room temperature or heated. In low-temperature winter, appropriate heating can accelerate vulcanization.

FAQ
Q: What chemicals should be avoided to prevent curing failure?
A: Avoid contact with organic tin compounds, sulfur/sulfides, amine compounds, incompletely cured condensation silicone, amine-cured epoxy resin and solder flux—these substances will inhibit curing.
Q: How to store this potting silicone properly?
A: Seal and store below 25℃, with a shelf life of 1 year. If stratification occurs, stir evenly before use; mixed glue should be used up at one time to avoid waste.
Q: Is it safe to transport and use?
A: It is non-hazardous and can be transported as general chemicals; avoid contact with mouth and eyes, and rinse with water immediately if accidentally contacted.
Q: Can it adapt to extreme temperature environments of aerospace?
A: Yes. It maintains elasticity in a wide temperature range, resists extreme cold and heat, and can stably operate in the harsh temperature environment of aerospace, protecting flight recorder components.
