Mix parts A and B in a simple 1:1 ratio. The black and white viscous liquids blend into a smooth material with a viscosity around 4000 mPa·s. This makes it easy to pour into molds or enclosures. Once mixed, you have about 50 minutes of working time at 25°C. Cure it fully in 10 hours at room temp or just 30 minutes at 60°C.

What sets this electronic potting silicone apart? It resists moisture, dust, and pollutants. It absorbs mechanical shocks and thermal stresses, reducing vibration damage. Plus, it’s solvent-free, producing no by-products during cure. The cured form maintains stable properties from -50°C to 250°C, ensuring long-term performance.

Repairing is straightforward too. If needed, you can access components without hassle. It boasts excellent electrical insulation, with dielectric strength over 25 kV/mm and volume resistivity at 1.0 × 10¹⁵ Ω·cm. Flame retardancy reaches UL-94 V-0, making it safe for high-risk applications.

How to use

For best results, stir components well before use. Vacuum degas after mixing to remove air bubbles. Avoid contact with substances containing nitrogen, sulfur, or heavy metals, as they might hinder curing. Store in cool, dry places for a one-year shelf life.

Engineers love this electronic potting silicone for its thermal conductivity of 0.8 W/m·K and low water absorption. It expands minimally with temperature changes, at 210 µm/(m·°C). Whether potting large volumes or thin layers, pour in stages for even results.

In automotive, aerospace, or consumer gadgets, Supex 2210 delivers. It’s non-hazardous for transport and comes in 10 kg pails per part. Choose electronic potting silicone that combines ease with endurance.

This compound excels in high-frequency electrical setups. Its dissipation factor is 0.01, and dielectric constant is 3.3 at 1MHz. Hardness hits Shore A 55, balancing flexibility and strength.

Overall, electronic potting silicone like Supex 2210 protects investments. It prevents failures from environmental factors, extending device life. With uniform mixing and proper curing, achieve optimal outcomes every time
