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.
