Room Temperature Curing Epoxy Resin for zero-sequence instrument transformers
Product TDS:
Epoxy Electrical Insulation System
| JT 8219A Epoxy Resin 100 pbw JT 8219B Epoxy Hardener 20-25 pbw |
| Used for:low voltage CT(and zero-sequence instrument transformers) |
| electronic components such as: ignition, regulator, electronic transformers, network transformers, pump motor, ignition coil, transformer, negative ion generator, AC capacitor, (vertical, horizontal, cartridge, film capacitor), power module, LED module, insulating pouring lamps etc. Appropriate operation time, easy to produce the work. Can withstand high and low temperature curve, with excellent electrical properties and physical properties. | Applications |
| For common vacuum casting processing, the typical mould temperature is 70℃–80℃, demoulding time( different as per temperature and volume) is about 5-8h. Keeping 10h at 130℃ after curing. Demoulding time and after-curing cycle need to be determined as per specific product design and technology. Please kindly contact our techanicians for more information | Processing methods |
| Room Temperature curing Good flame reardant Low viscosity Good impregnation Long pot life Good adhesion to the coil skeleton | Properties |

Remark:JT 8218 B contains accelerator. Prolonged storage at high ambient temperatures results in an undesirable increase in its viscosity and impairs the reactivity of the Casting Resin system.
JT 8218 B is sensitive to moisture. Partly emptied containers must be resealed immediately.
Storage*
The components have to be stored under dry conditions at 18-35°C, in tightly sealed original containers. Under these conditions, the shelf life will correspond to the expiry date stated on the label. After this date, the product may be processed only following reanalysis. Partly emptied containers should be closed tightly immediately after use.
For information on waste disposal and hazardous products of decomposition in the event of fire, refer to the Material Safety Data Sheets (MSDS) for these particular products.

Industrial hygiene
When operating and processing products, must follow the industrial hygiene standards.
For more information, please refer to the corresponding safety data sheet and .
Operating protection measures
Workplace safety measures:
Protective clothing Need
Gloves Must need
Arms to protection May contact with the skin, Recommended
Goggles/safety glasses Need
Mask/dust mask Recommended
Skin protection:
Before working To exposed skin protection by cream
After washing Frost of besmear protective cream or nutrition
Contamination of the skin clean With suction paper wipe, wash with warm water and alkali free soap, With a one-time towel dry. Do not use solvents.
Clean workshop environment Use a light paper covering the table and chairs. Using a disposable beaker, etc. Spatter material processing Use sawdust or waste cotton silk blotting, and placed in a plastic woven baskets.
Ventilation:
To workshop Take a breath three to five times per hour.
To position Cover of exhaust fan. The operator should avoid inhalation of vapour.
First aid
When the eyes by resin and curing agent and the contamination of cast table, immediately with a clean, running water rinse 10 to 15 minutes. To see a doctor. Touch or splash on the skin material to erase, and then clean with water pollution areas (see above). If severe pain or burn, want to see a doctor. Dirty clothes to replaced immediately.
Discomfort caused by inhalation of vapors, want instantly remove outdoor. If in doubt, please inquire the medical help.
