Room temperature curing epoxy resin system designed specifically for electrical insulation applications, particularly zero-sequence instrument transformers and low voltage current transformers.

JT 8219A/B epoxy resin system offers excellent electrical properties, physical characteristics, and thermal stability for demanding electrical insulation applications.

• Zero-sequence instrument transformers
• Low voltage current transformers (CT)
• Electronic components: ignition systems, regulators, transformers
• Network transformers, pump motors, ignition coils
• Negative ion generators, AC capacitors
• Power modules, LED modules, insulating pouring lamps

• Room temperature curing capability
• Good flame retardant properties
• Low viscosity for excellent impregnation
• Long pot life for extended working time
• Strong adhesion to coil skeletons
• Can withstand high and low temperature cycles

For vacuum casting processing: typical mold temperature 70-80°C, demolding time 5-8 hours (varies with temperature and volume). Post-cure at 130°C for 10 hours. Specific parameters should be determined based on product design and technology requirements.

Proper protective equipment including gloves, goggles, and appropriate ventilation is required. Refer to Material Safety Data Sheets (MSDS) for complete safety information.

Store in sealed containers at 18-35°C under dry conditions. Shelf life: 12 months from production date.
