Preparation
Because of the tendency to sedimentation of the filler,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. To facilitate stirring and removal, highly-filled components are heated to 60-80°C in the original container (e.g. overnight in an oven).
Mixing
To prepare the casting mix the resin component should be homogenized in holding tank A at 80-90°C under a vacuum of 1-5 mbar, the hardener component in holding tank B at 30-40°C and a vacuum of 1-5 mbar. A metering unit should be used to feed the resin and hardener components to an impeller mixer.
Curing
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 cure cycles in the customer’s manufacturing process could lead to a different degree of cross-linking and thus a different glass transition temperature.
