    Thermally Conductive Silicone Potting Compound SI2200 

    ◆Detailed Product Description

    SI2200 can be used for all kinds electronic components potting and protecting. It can be heated curing, operating time can be adjusted according to temperature.Good fluidity after mixed A and B.


    1.Two component and Molding silicone rubber

    2.Low speed on stiffness and shrinking

    3.Excellent electrical insulation on high temperature and good stability  

    4.Good property on waterproofing and damp-proofing

    5.Excellent adhesion property, curing time longer, the adhesion will be better


    For all kinds of electronics encapsulating and potting. Such as Automotive electronics module; Power control module; Solar junction box; Magnetic induction coil. Ceramic electrode; High voltage vacuum circuit breaker.

    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 10:1, 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 SI2200contact with sulfur, amine, tin material would be difficult to sclerosis.
