JT 8189A Epoxy Resin Curing Agent is a specialized liquid, hot-curing cast resin system designed for outdoor electrical insulation applications in medium and high voltage equipment, particularly current and potential transformers.
| Component | Ratio |
|---|---|
| JT 8189A Epoxy Resin | 100 pbw |
| JT 81859 Epoxy Hardener | 80 pbw |
| Silica filler (Silanised treated) | 300 pbw |
- Conventional casting with stage-wise curing
- Pressure gelation casting (PG process)
- Automatic pressure gelation casting (APG process)
- Excellent mechanical and electrical properties
- Superior temperature shock resistance
- Enhanced dielectric stability under high-humidity conditions
- Exceptional resistance to UV radiation erosion
Pre-filled resin or hardener has been pre-mixed with silica sands before delivery, simplifying your manufacturing process.
While pre-filled resin may appear cheaper initially, pure resin combined with locally sourced silica sands can be more cost-effective due to reduced shipping costs for the same resin quantity.
Our materials include flexibilizers and accelerators pre-mixed into the resin/hardener, ensuring easy application.
Please specify your process method (Vacuum Casting or Auto Pressure Gelation) when ordering, as we offer specialized formulations for each.
Different electrical characteristics require specialized formulations. We provide specific materials optimized for either current/potential transformers or bushings insulators.
Our materials are equivalent to Huntsman products. Provide the Huntsman product number you're currently using for exact matching.
Pre-filled resin: 1 year shelf life; Pure resin: 2-3 years shelf life.
Pre-filled resin: 25kg drums; Pure resin: 225kg drums; Additional options include 5kg drums and IBC tanks.
We provide comprehensive guidance and technical support based on extensive experience with thousands of manufacturers worldwide.
