①All data above were tested under standardized condition.

②All data listed in the chart were for the generalized item in the series; please refer to the related data sheet for special items.

③Storage condition has a direct impact to the products’ shelf life, Please refer to the instruction for special items’ storing


1.Mixing:Stirring A component evenly in the original package, then A, B components according to the weight ratio of 7:1 are weighed and mixed, then start to potting after mixing evenly .

2.The B component may appear crystal or caking during storage ( this is normal), if the crystallization need to placed in the oven at 80℃ to melt before using(the containers should be in open state,in order to avoid the gas expansion, damage container), and then cooling to room temperature before using, It does not affect its performance.

3.If necessary, the device with good sealing can continue to vacuumize , is helpful to increase the electrical properties of the device.

4.The curing conditions: 80 ℃/2hrs or 25 ℃/24hrs.

5.For the use of glue equipment please consult our marketing department.
