System Preparation
Because of the tendency for sedimentation of the fillers, pre-filled components in principle require stirring before removal from the original containers. To avoid errors in dosage, this step is especially important when removing only part of the contents. Prefilled ARALDITE® resins and hardeners can be heated to 40°C - 60°C in their original container to facilitate stirring and removal.
In the storage vessels of the production equipment, the pre-filled products should be stirred up from time to time to avoid sedimentation and subsequent possible irregular metering.
For better control of the thermal reaction and consistency during processing and curing, it is recommended to condition the ARADUR® hardener components to 18 - 22°C- Mixing and Curing Information
Mixing
In preparing the casting mixture, the ARADUR® hardener component is thoroughly stirred into the ARALDITE® resin component. Brief degassing of the casting mixture under a vacuum of 5 – 10 mbar improves homogeneity and enhances the dielectric properties of the casting.
Mixing of the components can be done at room temperature. Heating of the resin can lower its viscosity but will shorten the pot life.
Curing
To determine whether crosslinking has been carried to completion and the final properties are optimal, it is necessary to carry out relevant measurements on the actual cast object or to measure the glass transition temperature. Different gel and cure cycles in the customer’s manufacturing process could lead to a different degree of crosslinking and thus a different glass transition temperature.
Storage & Handling
- Storage Conditions
Storage
The components have to be stored under dry conditions at 2 - 40°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.
