IOTA 4926 Silicone sealant for new energy automotive safety power

    IOTA 4926 Silicone sealant for new energy automotive safety power

     

    Application:

    Widely used in new energy automotive power lithium battery PACK, waterproof, electronic components, heat sealing cushion.

    Used in various electrical equipment potting, positioning, bonding, waterproof and sealing .


    Product features:

    IOTA 4926 is a kind of double component silicone rubber, room temperature curing, can be heated fast curing. Its characteristics are as follows:

    Before curing, good fluidity, the operation time is moderate, good self deaeration, convenient operation and use;
    Excellent electrical insulation, arc resistance and shock resistance, long term protection of electronic components and welding points;
    Excellent thermal conductivity, can guarantee the effective heat dissipation of electronic components and batteries.

    Excellent high and low temperature resistance, after curing can be used for a long time under -50℃ ~+200℃;
