2-component epoxide resin
The epoxide resins for the isolator production have a very high mineral content, which results in a high viscosity (low fluidity). Affected by this guideline, the casting resins are preferably handled in a vacuum or in the pressure gelation process. The pressure gelation process equalizes the chemical volume loss, which occurs during curing.
The handling occurs with increased temperatures in order to obtain the corresponding flowing properties.
The high filling content is needed so that the moulding material comes as closest as possible to the heat expansion coefficients of the metal. The casting resins can be divided primarily into three groups:
Core area of difficult electronic applications:
• Generators and motors
• High voltage transformers
• Isolators and sockets
• Dry distribution transformers
