FAQ

1. What is the correct mixing ratio for 8822 A/B?
The mixing ratio is 1:1 by weight. Accurate weighing using an electronic scale is required to ensure proper curing and performance.

2. How long do I have to work with the mixture before it sets?
At a room temperature of 25°C, the pot life (operational time) for a 100g mixture is approximately 8 to 10 minutes. You should complete the pouring process within this timeframe.

3. How long does it take for the compound to fully cure?Surface Dry (Touch-free): 0.5 to 1 hour at 25°C.
Full Cure: 24 hours at 25°C to reach over 95% of its total hardness.
Heat Accelerated: Curing can be completed in as little as 13 minutes at 60°C.

4. Is this product fire-resistant?
Yes, 8822 is designed for high-safety applications . it is UL94 V0 flame retardant and halogen-free.

5. Can I use this for high-voltage electronic components?
Absolutely. It provides excellent electrical insulation with a dielectric strength of $\ge$ 50 kV/3mm.

6. Why does Part B need to be stirred before use?If Part B (the main agent) is left for more than one month, its internal oils and fillers may settle. Stirring ensures the material is evenly dispersed for consistent performance.

7. How should I store the product after opening?
Part A (Hardener): Extremely sensitive to moisture. After opening, it must be sealed with plastic wrap and a tight lid immediately to prevent self-curing.
Shelf Life: The sealed product has a shelf life of 6 months when stored in a cool, dry place between 5°C and 30°C.

8. What should I do if the material comes into contact with my skin or eyes?
Skin Contact: Wash the affected area thoroughly with soap and water.
Eye Contact: Immediately flush with large amounts of water for at least 15 minutes while keeping eyelids open, then seek medical attention.
