Pre - Filled Casting Epoxy Resin

PRE-FILLED CASTING EPOXY RESIN FOR DRY TYPE TRANSFORMERS CLASS F

PRODUCT DESCRITION:

JT8055A&B is liquid, latent, silica flour pre-filled, hot-curing cast resin system. Especially formulated for convenient in processing with excellent impregnating performance.

APPLICATION:

For dry type transformer

PROCESSING METHODS:

Conventional casting with stage wise curing, or pressure gelation or

Automatic pressure gelation casting (PG or APG process)

PROPERTIES:

1. Long pot life, short gel-time under high temperature

2. Excellent mechanical and electrical properties

3. Excellent crack resistance

PRODUCT TECHNICAL DATA:

JT 8055A Liquid, prefilled, solvent-free epoxy resin

JT 8055B Liquid, modified, prefilled and pre-accelerated anhydride hardener

JT 8055B 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. It is sensitive to moisture. Partly emptied containers must be resealed immediately.

Remark:

Prefilled liquid products always show small filler sedimentation. Before partial use, we

recommend to stir up carefully the components or to use each container as complete unity.

General instructions for preparing liquid resin systems

Long pot life is desirable in the processing of any casting resin system. Mix all of the components together very thoroughly at room temperature or slightly above and under vacuum. Intensive wetting of the filler is extremely important. Proper mixing will result in:

• Better flow properties and reduced tendency to shrinkage

• Lower internal stresses and therefore improved mechanical properties on object

• Improved partial discharge behavior in high voltage applications.

For the mixing of medium- to high viscous epoxy casting resin systems and for mixing at lower temperatures, we recommend special thin film degassing mixers that may produce additional self-heating of 10-15 K as a result of friction. For low viscous Epoxy casting resin systems, conventional anchor mixers are usually sufficient. The prefilled Epoxy resin and Hardener can be stored at elevated temperature (about 60°C) for up to about 1 week, de-pending on formulation. Intermittent agitation during storage is advisable to prevent filler sedimentation.

Mixing time can vary from 0.5 to 3 hours, depending on mixing temperature, quantity, mixing equipment and the particular application. The required vacuum is 0.5 to 8 mbar. The vapor pressure of the individual components should be taken into account

Dilute leftover mix at the end of a shift with the resin component prior to storage overnight or

over the weekend. Piping containing prefilled components or casting mixes should be cooled

immediately after work to prevent sedimentation and/or undesired viscosity increases. This

helps minimize material losses and cleaning work. If temperature cooling to under 18°C and

suspend working on weekend(about 48hours) and without cleaning, which is possible.

STORAGE:

The components have to be stored under dry conditions at 5 - 25°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, please refer to the Material Safety Data Sheets (MSDS) for these particular products.
