Prefilled BPA Resin | Thermal Shock Stability | Room Temp Cure
Engineered for outdoor CT/VT transformers, this prefilled Bisphenol-A epoxy system delivers vibration-resistant potting for 12-40.5kV coils exposed to extreme weather. LW-8224A resin + LW-8224B anhydride hardener provide crack-resistant encapsulation protecting delicate windings from mechanical stress, temperature swings (-40°C to 155°C), and environmental degradation.
Vibration Damping: Shields sensitive CT/PT coils from operational stress
Outdoor Endurance: Superior UV/weather resistance for transformers
Crack Resistance: Withstands thermal cycling in low/high temperature conditions
Prefilled System: Ready-to-use precision formulation
Energy-Efficient: Room temperature cure eliminates oven dependency
