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 uniformity in the packing before using.

2.Maxed A, B component as the weighing ratio of 1:1, mixing, and injected to the protection components (or modules) which need potting directly. In order to reduce the bubbles, injected slowly along the walls of the implement..

3.Let the components sit,out of bubble by themselves,heat curing or curing in the room temperature after the bubble disappeared,need about 5-6hours.

4.About potting equipment please contact our Marketing Department


1.It can improve the performance of the hardened by vacuum defoaming for mixed component.

2.After use, please seal the package.

3.The curing speed will be slow in the low temperature, suggest workshop in constant temperature.The temperature is too low will lead curing speed Pianman, the proposed workshop thermostat

4.Once SI2230contact with sulfur, amine, tin material would be difficult to sclerosis.
