Instructions:
Remove dirt, dust, oil, frost, etc. from the surface of the base material; place the plastic glue nozzle on the open
bottle mouth and tighten it, then use a glue gun to apply it on the surface of the base material from the hose.
In order to increase the curing speed and achieve complete curing faster, the product can be sprayed with
water evenly and appropriately before subsequent connection operations.
Precautions:
●After opening, it should be used up within one day, otherwise it must be tightly sealed and stored.
● Avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty
of water and see a doctor if necessary; avoid contact with children; do not contaminate food,
drugs or cosmetics.
Foaming occurs during the curing process. Pay attention to check and clean the spilled glue.
●Heavy bonded workpieces should be avoided from moving until they are completely cured. They must be moved.
Measures should be taken to secure it when moving.
● Recommended usage conditions: temperature 15~35℃, relative humidity 40%~80%;
If the humidity is lower than the recommended lower limit, the adhesive will cure slowly; if the humidity is higher than the recommended upper limit, application
Working hours will be shortened.
