Technical Details & Test Data
- Processing Data
ARALDITE® CW 1195-1 Resin and ARADUR® HW 1196 Hardener contains fillers which tend to settle over time. It is therefore necessary to carefully homogenize the complete contents of the container before use. To prevent filler separation and inconsistent metering, the components should be gently stirred from time to time while they are present in the production equipment storage tanks.

Curing
In manufacturing environment, the uncured impregnated parts will pick up moisture. Therefore, it is critical to fully cure the parts right after the impregnation or immediately store the uncured impregnated parts in a moisture-controlled area. To determine whether cross-linking has been carried to completion and the final properties are optimal, it is necessary to carry out some relevant measurements on the actual part or to measure the glass transition temperature of the cured system. Different gel and cure cycles in the manufacturing process are likely to lead to a different degree of crosslinking, hence different glass transition temperatures. The suggested curing process is 6 hours at 140 °C or 2 hours at 80 °C plus 6 hours at 140 °C to yield parts with low shrinkage and best surface aspect.

Araldite® CW 1195-1 Resin and Aradur® HW 1196 Hardener contains fillers which tend to settle over time. It is therefore necessary to carefully homogenize the complete contents of the container before use. To prevent filler separation and inconsistent metering, the components should be gently stirred from time to time while they are present in the production equipment storage tanks.
Mixing
To facilitate stirring and handling, highly filled components should be heated to 40 - 50°C in their original container (e.g. overnight in an oven) before adding the hardener. After a thorough mixing, the mixed material should be degassed under a 0.5 - 1 mbar vacuum to yield quality casting.

Safety & Health
- Safety Precautions
Huntsman Advanced Materials Americas LLC maintains up-to-date Safety Data Sheets (SDS) on all of its products. These sheets contain pertinent information that you may need to protect your employees and customers against any known health or safety hazards associated with our products. Users should review the latest MSDS to determine possible health hazards and appropriate precautions to implement prior to using this material.
Storage & Handling
- Storage Conditions
Araldite® CW 1195-1 Resin contains some curing catalyst and / or accelerator. It should preferably not be stored for long periods at temperatures exceeding 40°C nor should it be exposed to temperatures more than 100°C for more than 2 hours. Incorrect handling will result in an increase in viscosity and reduced performance properties of the cured system.
Araldite® CW 1195-1 Resin should be stored in a dry place, in their sealed original container, at temperatures between 2°C and 18°C (35.6°F and 164.4°F). Under these storage conditions the shelf life is 1.5 years (from date of manufacture). These products should not be exposed to direct sunlight.
Aradur® HW 1196 Hardener contains some curing catalysts and / or accelerators. Storage at elevated temperatures (>80°C) for extended periods (e.g. >5 days) will result in an undesirable increase in viscosity and will negatively affect the reactivity of the mixed system. This hardener is sensitive to moisture. Partially used containers should be closed immediately after use. Nitrogen blanketing is highly recommended as well as the use of a desiccant venting device unless the material is going to be used rapidly after opening.
Aradur® HW 1196 Hardener should be stored in a dry place, in their sealed original container, at temperatures between 2°C and 18°C (35.6°F and 64.4°F). Under these storage conditions the shelf life is 1.5 years (from date of manufacture). These products should not be exposed to direct sunlight. As with most pre-filled systems, the fillers present in these components have a tendency to separate during storage. This filler separation will not negatively affect the final product properties and quality provided that both components are thoroughly homogenized prior to use. The filled components should be stirred carefully using a low shear mixer prior to processing. Do not use high speed or high shear mixers or other equipment likely to cause air entrapment.
