Chemical Resistance	Excellent

Product Description

The LE-9219K/LH-9219K is a high-performance two-component epoxy resin system designed for medium/high-voltage electrical insulation (12-40.5 kV). Formulated with modified BPA epoxy resin (LE-9219K) and carboxylic anhydride hardener (LH-9219K), it delivers exceptional thermal shock resistance, superior crack resistance, and H-class thermal stability (IEC 60085). Ideal for vacuum casting or APG processes, it ensures reliability in critical indoor electrical components.

Key Features & Advantages

Feature	Advantage
Modified BPA Epoxy + Anhydride Hardener	Enhanced thermal stability & mechanical strength
Optimized for Vacuum Casting/APG	Flexible processing, adaptable to client production methods
Superior Crack Resistance	Withstands thermal cycling, reducing failure risks
HB Flammability Rating (UL94)	Meets strict safety standards for electrical applications
High Dielectric Strength	≥25 kV/mm (1mm thickness, IEC 60243-1)
Low Water Absorption	0.10-0.20% (23°C/10 days) for long-term insulation integrity
H-Class Thermal Endurance	Sustained performance up to 150°C

Applications

Perfect for insulating components in indoor high-voltage systems:

Switchgear contact boxes (12-40.5 kV)
Bushings, insulators, & encapsulation
Transformers, sensors, & circuit breakers
HV insulation products requiring precision casting

Frequently Asked Questions (FAQ)

Q1: What is the mix ratio for LE-9219K/LH-9219K?

A: Standard ratio is 100:100 pbw (resin:hardener). Filler (silica powder) added at 300-380 pbw.

Q2: How should the hardener be stored?

A: Store in sealed containers at 6-35°C. Avoid moisture exposure. If crystallized, preheat to 70-80°C and stir before use.

Q3: What curing process is recommended?

A: Two options:
Vacuum Casting: Cure 70-80°C/3-5h + 90-100°C/2-4h; Post-cure 130°C/12h.
APG: Mold temp 130-160°C; Post-cure 130-150°C/10-12h.

Q4: Is this system suitable for outdoor use?

A: Designed for indoor electrical insulation only. Hydrophobicity class HC1 (IEC TS 62073).

Q5: What safety measures are required during handling?

A: Mandatory: gloves, goggles, protective clothing. Use ventilation (3-5 air renewals/hour). Avoid skin contact--wash immediately if exposed.
