Usage Instructions for silicone potting compound:

1. Preparation:Clean surfaces to be potted, ensuring they are free of grease and dust.

2. Mixing:Precisely weigh components A and B in a 1:1 ratio by weight. Mix thoroughly in one direction until uniform in color.

3. Deaeration (Optional):For best results, vacuum degas the mixed compound (-0.095MPa, 5-10 minutes).

4. Potting:Slowly pour the compound into the assembly, allowing it to flow and fill naturally.

5. Curing:Allow to cure at room temperature, or heat at 80°C to accelerate the process.

Important Notes for silicone potting compound:

Always stir components A and B separately in their original containers before use.

Stir in one direction to avoid mixing in excessive air bubbles.

Strictly avoid contact with condensation-cure silicone rubbers, epoxy resins, or polyurethanes to prevent inhibition of cure ("poisoning").

Reseal containers immediately after use and store in a cool, dry place.

Packaging & Storage for silicone potting compound:

Standard Packaging: Component A 25kg/drum, Component B 25kg/drum.

Store in a cool, dry place. Shelf life: 6 months.

FAQ for silicone potting compound:

Q: What is the benefit of the 1:1 mix ratio?

A: It simplifies weighing, reduces errors, and improves production efficiency, especially for manual and fast-paced production.

Q: Is a thermal conductivity of 0.76 W/m·K sufficient?

A: Yes, it is suitable for thermal management in most power electronics, effectively reducing operating temperatures and improving reliability.

Q: What does the 94V-0 certification mean?

A: It means a 3mm test specimen self-extinguishes within 30 seconds after flame removal without dripping, providing a crucial safety guarantee.

Q: Is the pot life sufficient?

A: 0.3-0.4 hours is suitable for most small to medium-sized assemblies. For very large parts, segment potting or consulting us is recommended.

Q: Is specialized equipment needed?

A: Manual mixing is feasible, but for high-volume production, we highly recommend using a two-component metering and mixing system for guaranteed quality.
