Preparation
Because of the tendency to sedimentation of the filled resin and hardener 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.
To facilitate stirring and removal, highly filled components are heated to 50 to 70°C in the original container (e.g. overnight in an oven).
Process Parameters APG and Vacuum Casting processes
To prepare the casting mix, the resin component should be homogenized in holding tank A at 70 to 80°C under a vacuum of 1 to 5 mbar, the hardener component in holding tank B at 50 to 60°C and a vacuum of 2 to 5 mbar.Process Resin mix

3h/95°C + 2h/130°CTo 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 cure cycles in the customer’s manufacturing process could lead to a different degree of cross-linking and thus a different glass transition temperature.
- Applications

Storage & Handling
- Storage Conditions
Store the components in a dry place in tightly sealed original containers. Under these conditions, the shelf life will correspond to the expiry date stated on the label. Partly emptied containers should be tightly closed immediately after use.
