Environmentally Friendly Epoxy Resin System for Transformers & MV Switchgears

LE-8213 Epoxy Resin + LH-8213 Hardener

Product Overview

LE-8213/LH-8213 is a saturated cyclic aliphatic epoxy resin system engineered for high-voltage electrical insulation. Designed for sustainability and extreme reliability, this two-component system delivers exceptional thermal shock resistance (-40°C to +150°C), low curing shrinkage, and UV/weather stability. Ideal for encapsulating MV switchgears, dry-type transformers, and critical grid components.

Key Features & Benefits
