ARALDITE® CW 5817 resin should be heated in its original container to 50°C or 60°C in an oven. Pre-weigh the appropriate amount of resin component into a mixing vessel. According to the mixing ratio below, add the correct amount of ARADUR® HY 1235 hardener (at room temperature) followed by the correct amount of ACCELERATOR DY 062 (also at room temperature). The three components should then be mixed under a vacuum of 4 - 8 mbar at slight elevated temperature. The recommended mix temperature is 40 °C - 50 °C. Depending on the quantity mixed, mixer device, mixing temperature and application, the recommended mixing time is 0.25 to 1 hour. The effective pot-life of the mixed system is about 1 to 2 days at temperatures below 25 °C. Conventional batch mixers should be cleaned once a week or at the end of work. For longer interruptions of work, the pipes of the mixing and metering installations must be
cooled and cleaned with the resin component to prevent sedimentation and/or undesired viscosity increase. Interruptions over a weekend without cleaning are possible if the pipes are cooled at temperatures below 10 °C.

To determine whether cross-linking has been carried to completion and the final properties are optimal, it is necessary to carry out relevant measurements on the actual object or to measure the glass transition temperature. Different gel and post-curing cycles in the manufacturing process could influence the crosslinking and the glass transition temperature respectively.
Safety & Health

Storage & Handling
- Storage Conditions
Araldite® CW 5817 Resin contains cure-accelerating additives. It should not be stored for long periods at temperatures in excess of 30°C (86°F), nor should it be exposed to temperatures in excess of 100°C (212°F) for more than 2 hours. Incorrect handling will result in an increase in viscosity and reduced cured-state properties.
Aradur® HY 1235 Hardener is moisture sensitive. 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. For Accelerator DY 062, if only part of container is used, re-close to prevent contamination.
Araldite® CW 5817 US / HY 1255 / DY 062 system should be stored in a dry place, in the sealed original container, between 2°C and 40°C Under these storage conditions, the shelf life is 1 year (from date of manufacture). The 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. The filled components should be stirred carefully by using a low shear mixer prior to processing. Do not use high speed or high shear mixers and take precautions to prevent air entrapment.
