JT 8048B contains accelerator. Prolonged storage at high ambient temperatures results in an undesirable increase in its viscosity and impairs the reactivity of the system mix.

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

 

 

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, refer to the Material Safety Data Sheets (MSDS) for these particular products.

  Processing (guideline values)  

General instructions for preparing liquid resin systems

Long pot life is desirable in the processing of any ARALDITE 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 vapour pressure of the individual components should be taken into account.

 

 

System Preparation

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.

 

For the processing viscous data and gel-time under different temperature, please kindly refer to Figure 4.1 and 4.4 as following showing:

 

Mould temperature

APG process 140 - 160°C

Conventional vacuum casting 70 - 100°C

 

Demoulding times (depending on mould temperature and casting volume)

APG process 10 - 40 min

Conventional vacuum casting 5 - 8h

 

Cure conditions

APG process (minimal postcure) 4h at 130°C or 3h at 140°C

Conventional vacuum casting 12h at 130°C or 8h at 140°C

 

To determine whether crosslinking has been carried to completion and the final proper-ties are optimal, it is necessary to carry out relevant measurements on the actual object or to measure the glass transition temperature. Different gel and postcuring cycles in the manufacturing process could influence the crosslinking and the glass transition temperature respectively.

Industrial hygiene

Follow the industrial hygiene standards when operating and processing products

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 castable, 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, please see the doctor. Replace the dirty clothes immediately.

Discomfort caused by inhalation of vapors, remove outdoor immediately. If in doubt, please inquire the medical help.
