🔬 Processing advice for Battery Potting
Step-by-step process:
Preparation - Clean battery cells and housing, remove grease and dust
Primer (optional) - Apply primer for optimal adhesion to metal/plastic
Mixing - Use Sulzer Mixpac dispenser for precise mixing ratios
Bleeding - Remove air bubbles by vacuum or letting it stand
Pouring/Injecting - Apply potting compound between and over the cells
Curing - At room temperature or accelerated at 40-80°C
Testing - Check insulation and thermal properties
Tips for optimal results:
Work at 18-25°C for best flow properties
Use thermally conductive fillers for better heat dissipation
Choose closed cell foam for gap filling (prevents electrolyte absorption)
Always test on a small scale before production
Consider two-step potting: first gap filling, then full encapsulation

💡 Frequently Asked Questions
What is the difference between potting and conformal coating? Potting fills the entire space around components, while conformal coating provides a thin protective layer. For batteries, potting is more effective for thermal management and mechanical protection.
Which hardness should I choose? For gap filling: Shore A 10-30 (soft, flexible) For full encapsulation: Shore A 30-50 (medium) For structural support: Shore A 50-70 (hard)
Can I increase thermal conductivity? Yes, by adding thermally conductive fillers such as aluminum oxide or by using Silso Cool Thermal Pastes.
How do I remove silicone potting for repair? Silicone can be removed mechanically by cutting. For easier repair, you can choose softer compounds (Shore A 10-20).
