    ◆Operation and Attention


    1.Cleaning: cleaning the surfaces that to be glued and coated, removing the rust, dust, greasy dirt and other foreign matter and substance.

    2.Gluing: cutting nozzle to the required angle, extruding the liquid cement to the cleaned surface and making it well-distributed, then folding and fixing the glued surfaces.

    3.Curing: placing the glued or sealed components in the air to make them cured naturally. Curing is a process that being cured from surface to the internal.The sealant will be cured at a depth of 2~4mm within 24 hours (at room temperature and 55% relative humidity), if the glue position is deeper, especially the parts that not easy to come into the air,the time that being completely cured will be longer, if the temperature is low, the curing time will also be extended. It will take more than 7 days to make 6 mm thick sealant fully cured


    1.Tightening and sealing the leftover sealant after the operation.        

    2.Removing the cured cement at the sealing part that might happen during the   preservation, it could be normally used again.

    ◆Package and Storage


    310ml cartridge, 20pcs/carton


    1.Kept in cool and dry place(≤35℃),the shelf life is 12 months when stored below 25℃.

    2.Not restricted. Looking out the leakage in the process of transportation.

    3.Confirming the condition of the products that out of deadline before using.

    ◆Safety Operation Material

    MSDS isn't included here. Please read TDS, MSDS and label carefully before operation.You can get MSDS from

    Sepuna or other distributors, or mail to service center, or call +86-400-882-1323.
