■Usage and precautions
※The adhesive sealing surface should be clean, the top of the nozzle should be cut off and sealed according to the dosage, put it on the packaging mouth, apply it to the construction surface (thickness should not exceed 6mm), and put it in the air. The surface of this product can lose its adhesive shape (surface dry) at room temperature for 3-10 minutes, and it will be completely cured after 24 hours. The heating of this product can not significantly change its curing speed.
※Unused adhesive material should be sealed and stored. When used again, if there is a little crust at the seal, it can be removed without affecting normal use. Glue in the storage process, the nozzle may also appear a small amount of curing phenomenon, can be removed after normal use, does not affect the performance of the product. The storage period is 6 months (25℃).
※This product is non-dangerous goods, but do not import and eye.
※This product cannot be mixed with other types of colloids!
