Product Description

Product Description

HY484 Epoxy Potting Compound : Comprehensive Encapsulation & Protection for Electronic Components

HY484 is a premium series of two-component, room-temperature curing epoxy resin systems designed for the potting, sealing, and insulation of sensitive electronic assemblies. Known for its exceptional self-leveling properties and high hardness, HY484 protective barrier against moisture, vibration, and electrical breakdown. Whether you need optical clarity for LEDs or high-power thermal management, the HY484 series offers a specialized grade to ensure the longevity of your PCBAs and modules.

Product Features 

1,Superior Electrical Insulation: Engineered with high dielectric strength to prevent electrical leakage and short circuits in high-density components.

2,Exceptional Hardness & Mechanical Protection: Cures to a high-strength solid (Shore D ≥ 80) that resists physical impact, vibration, and environmental stress.

3,Excellent Self-Leveling: Low-viscosity formula ensures deep penetration into complex gaps and bubble-free encapsulation.

4,Environmental Resilience: Solvent-free and low-VOC; provides long-term resistance to aging, moisture, and UV degradation.

5,Non-Corrosive: Completely safe for delicate electronic circuits, copper wiring, and semiconductor materials.

Primary Applications 

1,Power Electronics: Encapsulation of power supplies, converters, and transformers.

2,Automotive Electronics: Protection of sensors, igniters, and control units against engine heat and moisture.

3,Lighting Industry: Potting of LED drivers and outdoor lighting modules (HY484T).

4,Industrial Automation: Sealing of PCBAs in controllers and communication equipment.

Core Advantages for Global Buyers

1,Low Shrinkage Rate: Ensures minimal internal stress on sensitive components during the curing process, preventing circuit failure or component displacement.

2,High-Efficiency Production: Optimized pot life (30-60 mins) allows for large-batch production while maintaining easy flowability before curing.

3,Global Safety Standards: Formulated to be eco-friendly and compliant with modern industrial safety regulations, making it suitable for export-oriented electronics.

4.Storage: Keep in a cool, dry place (5 ℃ to 23℃ ). Shelf life is 6-12 months.
