Product Overview
Our Flame Retardant Electronic Potting Compound is a professional fire-safe potting material for electronic components, a key part of HONG YE SILICONE’s full silicone product matrix. Model HY-9045 is an addition curing flame-retardant silicone, which is a new type of flame-retardant material. It is liquid before mixing, cures into a stable, low-shrinkage protective layer after blending Component A and B at 1:1 weight ratio. Different from ordinary Electronic Potting Compound, it focuses on fire safety, forming a reliable flame-retardant system while providing full-range protection, solving the pain points of electronic component fire risks in high-temperature or high-voltage scenarios. Product Features & Advantages
1. Superior flame retardancy (core advantage): Integrates excellent flame-retardant performance, forming a flame-retardant system to prevent fire spread, paired with high insulation (volume resistance ≥1×10¹⁵ Ω, dielectric strength ≥25 kv/m⁻¹), ensuring safe operation of electronic components in high-risk scenarios.
2. Gentle & flexible curing: Cures without exotherm, no corrosion to electronic components, low shrinkage; supports both room-temperature and heating curing (80℃ for 4-5 hours), adaptable to manual operation and automated production lines, even accelerable in low winter temperatures.
3. All-round protection & stability: Combines waterproof, moisture-proof, mold-proof and dust-proof properties, with excellent chemical medium resistance, yellowing resistance and weather aging resistance, maintaining stable performance in diverse environments.
4. Easy operation & high compatibility: 1:1 weight mixing ratio (easy to measure), Component A and B are both liquid; after mixing, deaeration at 0.08MPa for 3 minutes ensures bubble-free potting, compatible with various electronic substrates.
5. Customizable & cost-saving: Key parameters (hardness, viscosity, operable time) can be adjusted according to needs; mixed glue should be used at one time to avoid waste, reducing procurement and production costs for manufacturers.
Technical Specifications (Model HY-9045)
This product is an addition curing flame-retardant electronic potting compound, with Component A and B both being liquid. The mixing ratio is 1:1 by weight, Component A has a viscosity of 2500±500 Pa.s. At 25℃, the operable time is 30-60 minutes; at 80℃, the curing time is 4-5 hours. After curing, it reaches Shore A hardness 45±5, dielectric strength ≥25 kv/m⁻¹, dielectric constant 3.0 (1.2MHz), volume resistance ≥1×10¹⁵ Ω. These parameters are for HY-9045; other models and customizable parameters (hardness, viscosity, operable time) are available on request.
How to Use
1. Preparation: Fully stir Component A and B separately in their respective containers to ensure uniform material composition without stratification, which is critical for stable flame-retardant and curing performance.
2. Mixing: Blend Component A and B strictly according to 1:1 weight ratio, stir thoroughly to guarantee consistent flame retardancy and insulation performance of the cured layer.
3. Deaeration: After mixing evenly, place the glue into a vacuum container and deaerate for 3 minutes under 0.08MPa to remove air bubbles, ensuring a dense, bubble-free potting layer.
4. Potting & Curing: Pour the treated silicone onto target electronic components; choose room-temperature curing or heating curing (80℃ for 4-5 hours). In low winter temperatures, proper heating can be used to accelerate vulcanization for efficient production.
Application Scenarios
