2. Superior waterproof & insulation performance: Delivers excellent waterproof, moisture-proof and dust-proof effects, paired with high insulation (volume resistivity ≥1.0×10¹⁶ Ω·cm, dielectric strength ≥25 KV/mm), ideal for outdoor LED displays.
3. UL94-V1 flame retardancy & EU ROHS compliance: Meets strict flame retardant standards to reduce fire risks, fully complies with EU environmental directives, supporting global LED market access.
4. Strong adhesion & wide compatibility: Excellent bonding performance to PC, PP, ABS, PVC and various metals, ensuring tight adhesion to LED substrates and modules without peeling or cracking.
5. Easy operation &量产-friendly: Low viscosity, 1:1 weight mixing ratio (easy to measure), optional vacuum defoaming; room-temperature curing (3-5h basic, 12-24h full), adaptable to LED mass production lines, reducing production costs.
Technical Specifications (HY-9055)
It is a two-component potting compound with Component A and B both being liquid, Component A has a dynamic viscosity of 3000±500, mixed at 1:1 weight ratio. Mixed operable time is 30-120 minutes, basic curing time 3-5 hours, full curing time 12-24 hours. Cured hardness is Shore A 55±5, thermal conductivity ≥0.4 W(m·K), dielectric constant 3.0~3.3 (1.2MHz), volume resistivity ≥1.0×10¹⁶ Ω·cm, flame retardancy UL94-V1, with excellent adhesion. These parameters are for HY-9055; other models and customizable parameters (hardness, viscosity, curing time) are available for different LED applications.
How to Use
1. Preparation: Fully stir Component A to mix settled fillers evenly; shake Component B thoroughly to ensure uniform material composition without stratification, critical for LED potting uniformity.
2. Mixing: Blend Component A and B strictly according to 1:1 weight ratio, stir thoroughly to guarantee consistent thermal conductivity and curing performance for LED components.
3. Deaeration (Optional): Place the mixed liquid into a vacuum container, deaerate for 3 minutes under 0.08MPa to remove air bubbles, avoiding bubble-induced light refraction or heat accumulation in LED modules.
4. Potting & Curing: Pour the treated compound onto LED modules or electrical components, place at room temperature for curing. Proceed to the next process after basic curing; full curing (12-24h) ensures optimal protection for LED applications.
