Product Overview
Our Battery Module Electronic Potting Silicone Compound is a professional potting material tailored for battery module protection, a key part of HONG YE SILICONE’s full silicone product matrix. Model HY-9055 is a two-component organic silicone sealant with low viscosity, designed to solve battery module pain points—heat accumulation, leak-proof risk, high-voltage safety and component loosening. It is liquid before mixing (Component A and B are both liquid), cures into a dense, high-adhesion protective layer, forming a reliable insulation and heat-dissipating system to ensure stable, safe operation of battery modules, far exceeding ordinary Electronic Potting Compound in battery module application adaptability. Product Features & Advantages
1. Battery module-specific thermal conductivity: Thermal conductivity ≥0.4 W(m·k), efficiently dissipates heat generated by battery cells during charging and discharging, balances internal temperature of battery modules, reduces thermal runaway risk and extends battery service life.
2. Superior high-voltage insulation & flame retardancy: Volume resistivity ≥1.0×10¹⁶ Ω·cm, dielectric strength ≥25 KV/mm, effectively resisting high-voltage breakdown; meets UL94-V1 flame retardant grade, further ensuring battery module safety in extreme conditions.
3. Leak-proof & strong adhesion: Low viscosity with good fluidity, fills gaps between battery cells and components seamlessly after potting; excellent adhesion to battery module substrates (PC, PP, metals), forming a leak-proof barrier to prevent electrolyte leakage.
4. Gentle curing & production-friendly: Room-temperature curing (full curing 12-24 hours, basic curing 3-5 hours), no exotherm or corrosion to fragile battery components; curing effect is affected by temperature and humidity, adaptable to automated battery module production lines.
5. Easy operation & cost-saving: 1:1 weight mixing ratio (easy to measure), optional deaeration at 0.08MPa for 3 minutes ensures bubble-free potting; mixed glue should be used at one time to avoid waste, reducing procurement and production costs.
Technical Specifications (Model HY-9055)
This product is a two-component battery module potting silicone, with Component A and B both being liquid; Component A has a dynamic viscosity of 3000±500.

Other models and customizable parameters (hardness, viscosity, operation time) are available on request.
How to Use
1. Preparation: Fully stir Component A in its container to mix settled fillers evenly; shake Component B thoroughly to ensure uniform material composition without stratification, critical for stable thermal conductivity and leak-proof performance.
2. Mixing: Blend Component A and B strictly according to 1:1 weight ratio, stir thoroughly to guarantee consistent insulation, thermal conductivity and curing performance for battery modules.
3. Deaeration (Optional): After mixing evenly, place the mixed liquid into a vacuum container and deaerate for 3 minutes under 0.08MPa to remove air bubbles, avoiding heat accumulation and insulation failure caused by bubbles.
4. Potting & Curing: Pour the treated silicone onto battery modules, covering gaps between cells and components; place at room temperature for curing. Proceed to the next process after basic curing, and ensure 12-24 hours for full curing to achieve optimal protection effect.
