Operation
1. Stirring A component evenly before using it .
2. Weighed in a 5:1 ratio A, B two components, stir well stay with after vacuum deaeration to use within 60 minutes run out.
3. Good potting devices ,if necessary, continue to pumping vacuum, help to increase the electrical performance of the device.
4. Curing conditions: 25°C for 24hrs at room temperature ; or let stand for surface bubbles after heating 65 °C× 0.5hr.
5. Note: adhesive start the reaction after adhesive preparation , accompanied by heat release. With the greater amount of glue, the greater the heat release, the shorter operating time, required in a shorter period of time you are finished using
6.The above tests are measured under 100 g with adhesive
