Note:
- Theabovedata curing conditions tested were 100 ℃ * 2h
- The measured data table is under a specific condition, for reference, the resulting data does not guarantee that theclient can fully consistent with theactual use.
Operation process
l Preparation: Put A material original packaging barrels at 40℃ environment preservation 2 hours, after take out, compound viscosity is thinning, lower.
l Or use directly at normal room temperature.
l Mixing :With the A component of the filler will contain the time to precipitate down, so use a stirrer to make the filler and resin liquid mixed evenly. ThenweighingA / B components with Ratio 100:8, mixingthoroughly for several minutes. After, the finished liquid will be ready for potting.
l Component B may occur during storage or agglomeration of crystal (a normal case), if required before use crystalline placed in an oven at 60 ℃to melt it, and then cooled to room temperature and after use, which does not affect its performance.
l The exposed component B will be hydrolyzed in moisture and the color of hydrolysate will show the color of white as friable powder.
l Good potting device, if necessary, vacuum may continue to help increase the electrical properties of
the device.
Apply for electronic componets
Curing conditions
Recommendedcuring process would be chosen as below:
25℃* 24h at room temperature
80℃ * 3h
100℃ * 2h, reach the heat resistance grade B;
100 ℃ * 2h + 120 ℃ * 1h , reach the heat resistance grade F;
If working temperature is below 150 ℃ , the final curing temperature can be ignored.
Packing and Stocking
l Avoid the sun and heat, stock under sealing.
l Shelf life at 25τ: Part A 12 months, part B 12 months;
l If expired should be tested first.
l Part A :20kg/plastic drum; Part B: 0.8kg/bottle or 2.4kg/pot
