Product Description

Crystal Clear Epoxy Resin Liquid for Electrical Components & Insulation

LW-9229A/B: Crack-Resistant Room Temp Cure Epoxy for 10-35kV CT/PT Insulation & Outdoor Encapsulation

UL-Certified | Pre-Mixed Fillers | Superior Dielectric Strength

Engineered for outdoor electrical insulation in Current Transformers (CT) and Potential Transformers (PT), this modified BPA epoxy system delivers crack-resistant encapsulation for 10-35kV terminal posts, bushings, and transformer components. With pre-mixed fillers in both resin (LW-9229A) and hardener (LW-9229B), it ensures consistent thermal shock resistance and long-term durability in harsh environments.

Key Advantages

Crack Resistance: Withstands thermal cycling for outdoor applications.
High Dielectric Strength: Critical for 10-35kV insulation systems.
Pre-Mixed Fillers: Simplified processing, no weighing errors.
Room Temperature Cure: Energy-efficient transformer manufacturing.
Moisture & Chemical Resistance: Protects CT/PT units from environmental degradation.

Applications

Ideal for:

10-35kV sealed terminal posts
CT/PT transformer potting & coil encapsulation
Outdoor bushings, insulators, switchgear
High-voltage electrical insulation components
