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 3 days to make 6 mm thick sealant fully cured.

Note: Using up the sealant as far as possible once opened. Edging out the cured part to make normal use if it has not been finished. Please consult PUNADE market department when using dispensing equipment.
