Electrical Insulation Silicone Potting Compound For Power Modules And Inverters

Product Overview for Silicone Potting Compound:

HN-8808, two parts, low viscosity potting compound that cures at room temperature to soft pliable rubber. 1. This potting silicone rubber has high moisture resistance and a wide temperature range of - 57°C to 250°C.

Key Performance Parameters for Silicone Potting Compound:

1. Pot Life (25°C): 40–60 minutes — Delivers an extended processing window for continuous assembly.

2. Mixed Viscosity: 2000–2600 cP — Optimizes self-leveling penetration while resisting run-off.

3. Mix Ratio: 10:1 — Lowers sensitivity to scaling errors, enhancing production yield.

4. Curing Profile: Ambient cure — Negates the need for ovens, reducing energy and capital costs.

5. Post-Cure Hardness: 30–40 Shore A — Yields moderate elasticity to optimize post-assembly reworkability.

Product Highlights for Silicone Potting Compound:

1.Condensed liquid silicone rubber does not use polar compounds as raw materials, and does not release by-products during cross-linking, and can maintain better electrical properties under harsh conditions.

2. Non-toxic, odorless, non-corrosive, non-swelling.

3. It has adhesive force, has adhesion to metal aluminum, iron, acrylic, and PC plastic, and can improve waterproof sealing performance.

Application Areas for Silicone Potting Compound:

Widely used in sealing, electrical, potting, insulation, antifouling, waterproof, shockproof, coating, electronic appliances, and comprehensive household appliances.

Detailed Operating Guide (Manual Operation Focus) for Silicone Potting Compound:

1. Tool Prep: Ready two clean plastic/paper cups and a high-precision scale.

2. Tare Weighing: Place cup, tare, and add 100g of Part A. Tare again, then add 10g of Part B to eliminate container error.

3. "Figure-8" Mix: Use a flat-head stirrer. Mix slowly in a figure-8 pattern for 3 full minutes, scraping the sides and bottom thoroughly.

4. Simple Degassing: If lacking a vacuum, let sit for a few minutes. Pop surface bubbles with a toothpick or a light pass of hot air.

5. Corner Pour: Pour into a single corner to allow natural self-leveling. For tall parts, fill halfway, let gel slightly, then fill to the top to prevent trapped air.

Packaging & Storage for Silicone Potting Compound:

1. Standard Packaging: 22kg/set; 11kg/set. Smaller packages suit flexible production needs.

2. Storage Conditions: Store in a cool, dry place.

3. Shelf Life: 6 months in original, unopened containers from date of manufacture.
