    Remarks:

    1、The using way is same with common colloidal silica.
    2、The life of slurry, the capability of coating and the high-temp strength are similar with common colloidal silica.

    3. The shell should be uniform by wind in drying process.

    4、Please park 24 hours before dewaxing.
    5、It can replace ethyl orthosilicate, and its high-temp strength is higher.
    6、It can replace the mixer of colloidal silica and latex.
