Product Description
Product Overview
JT 8209A/B Clear Liquid Epoxy Resin System is a two-component electrical insulation compound designed for potting and casting applications. This system offers excellent electrical properties, thermal stability, and mechanical strength for various electronic components.
Applications
- Low voltage CT and zero-sequence instrument transformers
- Electronic components including ignition systems, regulators, and transformers
- Network transformers, pump motors, and ignition coils
- Negative ion generators and AC capacitors
- Power modules, LED modules, and insulating pouring lamps
Processing Methods
For vacuum casting processing, typical mold temperature is 70-80°C with demolding time of 5-8 hours. Post-curing requires 10 hours at 130°C. Specific parameters should be determined based on product design and technology requirements.
Key Properties
- Room temperature curing capability
- Good flame retardant properties
- Low viscosity for excellent impregnation
- Extended pot life for easy processing
- Strong adhesion to coil skeletons
