How to use

Process of use:

Clean the surface: will be glued or coated surface clean, and remove rust, dust and oil.
Sizing: unscrew (or cut) the cap of the hose, squeeze the glue liquid to the cleaned surface, make it evenly distributed, and close the adhesive surface to fix it.
Curing: Place the glued or sealed part in the air and let it cure naturally. The curing process is a curing process from the surface to the inside, within 24 hours (room temperature and 55% relative humidity) the glue will cure the depth of 3 ~ 4mm, if the glue position is deep, especially the part that is not easy to access the air, the full curing time will be extended, if the temperature is low, the curing time will also be extended, 6mm thick sealant completely
