Product Description

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.

Key Features & Benefits
  • 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.

Frequently Asked Questions
Why is the hardener's viscosity lower than the resin's?

LH-8516's lower viscosity (200-500 mPa.s) improves filler (e.g., silica flour) dispersion and reduces air entrapment during mixing.

Can I adjust the filler loading beyond 350 pbw?

Exceeding 350 pbw may compromise mechanical properties. Conduct trials for your specific application.

Is post-curing mandatory?

Yes. Post-cure (130-140°C × 6-10 hrs) ensures full crosslinking and optimal thermal/electrical performance.

How does this system compare to amine-cured epoxies?

Anhydride curing offers lower exotherm, reduced shrinkage, and better UV resistance vs. amines.

What safety precautions are required?

Use PPE (gloves, goggles); ensure ventilation (vapor pressure: resin 0.5 Pa, hardener <0.01 Pa)
