Epoxy Resin LE-8516 and Hardener LH-8516 form a modified, weather-resistant anhydride-cured system designed for demanding industrial applications. With a 1:1 mixing ratio by weight, this combination delivers exceptional mechanical strength, thermal stability, and electrical insulation—ideal for coatings, encapsulation, and structural composites.
✔ Optimized Viscosity Pairing – LE-8516 (500-1000 mPa.s) + LH-8516
(200-500 mPa.s) ensures easy mixing and filler wetting.
✔ High Thermal Resistance – Glass transition (Tg) 60-80°C; thermal
decomposition >320°C.
✔ Low Shrinkage (0.8-1.0%) – Minimizes stress in precision
components.
✔ Superior Dielectric Properties – Volume resistivity: 10¹⁵ Ω·cm;
dielectric strength: 20-30 kV/mm.
✔ Weather & Chemical Resistance – Anhydride hardener enhances
UV/acid durability.
| Epoxy Resin LE-8516 | Hardener LH-8516 |
|---|---|
| Appearance: Transparent, pale yellow, viscous liquid | Appearance: Transparent, pale yellow liquid |
| Epoxy Value: 4.5-5.0 Eq/kg | Viscosity at 25°C: 200-500 mPa.s |
| Viscosity at 25°C: 500-1000 mPa.s | Density at 25°C: 1.16-1.20 g/cm³ |
| Density at 25°C: 1.17-1.24 g/cm³ | Flash Point: ~135°C |
| Flash Point: ~140°C | Vapor Pressure at 25°C: <0.01 Pa |
| Vapor Pressure at 25°C: ~0.5 Pa |
A: LH-8516’s lower viscosity (200-500 mPa.s) improves filler (e.g., silica flour) dispersion and reduces air entrapment during mixing.
A: Exceeding 350 pbw may compromise mechanical properties. Conduct trials for your specific application.
A: Yes. Post-cure (130-140°C × 6-10 hrs) ensures full crosslinking and optimal thermal/electrical performance.
A: Anhydride curing offers lower exotherm, reduced shrinkage, and better UV resistance vs. amines.
A: Use PPE (gloves, goggles); ensure ventilation (vapor pressure: resin 0.5 Pa, hardener <0.01 Pa)
