    ROSH thermal conductivity encapsulation silicone for led / CPU

    1. Product features

    ZS-NJ-D935W is one kinds of the thermal type of one-component alcohol silicone sealant which is Room temperature curing. This products have the properties such as high strength, good adhesion, good adhesion on alumina, copper, stainess steel and other metal, excellent dielectric and good heat resistance. The general use of temperature range is from -60℃~200℃. During the curing process, it will release the alcohols, which with no corrosion to the materials such as polycarbonate(PC) and copper. Absolutely compliance with the EU RoHS’s requisition.

    2. The typical use

    Chip and heat sink bonding; thyristor intelligent control module and heat sink bonding; between module and heat sink filled with high-power electrical bonding.

    3. Technical Parameters

    Before curing


    White paste

    Relative density(g/cm3)


    Tack-free time (min)



    Tensile strength(MPa)


    Break elongation(%)


    Shear strength(MPa)


    Hardness(Shore A)


    Temperature Range(℃)


    Volume resistivity (Ω·cm)


    Dielectric strength (kV/mm)

    The above performance data are at 25 ℃, 55% relative humidity measured after 7 days curing. The company tested different conditions or product improvements resulting from different data assumes no responsibility.

    1. The use of technology

    4.1 Surface cleaning:cleaning the sticklied and coated surface,remove the rust,dirt and oil.

    4.2 Brush the glue: Unscrew the hose cap (or cut open), pushed the glue to clean the surface, evenly distributed so that will be glued surfaces together and fixed.

    4.3 Curing: put the glued or sealed parts in the air and let it be natural cured. It’s one curing process that cured from the surface to the internal, in less than 24 hours (at room temperature and 55% relative humidity) glue curing depth of 2 ~ 4mm, if the sizing location more deeper, in particular, which is not easily accessible to the air, then the fully curing time will be extended, if the temperature is low, the curing time will be extended too, sealant is fully cured at least 7 days if the thick have 6mm .

    5. Precautions

    After operating, unused glue must be sealed and stored , and tighten the cap immediately,. if the seal has a little crust when use it in the next time, remove it and it will not affect the normal use. During the storage process, the canal orifices may appear a small amount of the curing phenomenon, cleared it and it can use it again, and no affection to the product performance.


    100mL / tube,100tubes / box.

    7. Storage and transportation

    1. 25 ℃ in a cool dry environment six months, more than the shelf life of the product should be confirmed before use after no exception.

    2. Such products are non-dangerous goods, can be transported as common chemicals. Be careful during transport and prevent the leakage.

    8. Recommendations and statements

    Users are advised to use this product to do first before the formal suitability test.Because of the diversity of practical application, our company does not guarantee specific conditions of use of our products emerging issues, is not liable for any direct, indirect or accidental loss of user in the course of any problems, you can contact our service department We will try to assist you.
