Operation process

Preparation: Put A material original packaging barrels at 40℃ environment preservation 2 hours, after take out, compound viscosity is thinning, lower.

Or use directly at normal room temperature.

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.

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.

The exposed component B will be hydrolyzed in moisture and the color of hydrolysate will show the color of white as friable powder.

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

Avoid the sun and heat, stock under sealing.

Shelf life at 25τ: Part A 12 months, part B 12 months;

If expired should be tested first.

Part A :20kg/plastic drum; Part B: 0.8kg/bottle or 2.4kg/pot
