    STORAGE AND SHELF LIFE

    IOTA 4808 should be stored in original unopened containers over temperature from 4℃to 27℃ and be kept away from rain or direct sunshine.

    IOTA 4808 has a shelf life of 12 months from the date of manufacture.

    IOTA 4808 is non-hazardous for transportation.

     

    HOW TO USE

    Mix part A base to Part B curing agent at a ratio of 6:1 by weight or 4:1 by volume, and then pot the mixture into the parts of substrates where needed, place at room temperature for initial curing for about 2~4 hours before conducting the next procedure. If precipitation occurs in Part A, just stir it well before use, and this does not affect the performance of the sealant.

    When using automatic dispensing machine, set at a ratio of 6:1 by weight or 4:1 by volume of part A to Part B for a test first and then put into use.

     

    NOTES

    Screw tight the cover of Part B immediately after use to avoid the exposure to atmospheric moisture

    Part A base and part B curing agent should be fully mixed to ensure the homogenity of the sealant, or it affects the performance of the sealant.

    Part A and Part B should be kept separately and get mixed on site, and be used within a short time after mixing.

    For common low-voltage electrical potting, de-bubbling is not needed, but vacuum de-bubbling for 3~5 minutes is required for high voltage electrical potting.
