  Store
  Can be stored for 6 months in a cool, ventilated and dry place.
  
  Precautions and precautions
  The initial 20g of mixed glue may be insufficiently mixed and is not recommended.
  The glue mixed at room temperature should be used during the application period.
  Avoid contact with skin and eyes. If inadvertently, rinse immediately with plenty of water and consult a doctor if necessary;
  avoid contact with children; do not contaminate food, medicine or cosmetics.
  The heavy workpiece to be bonded should be avoided to move before it is completely cured, and measures should be taken to fix it when it is necessary to move.
  Recommended use conditions: temperature 15 ~ 35C, relative humidity 40% ~ 80%; if the temperature and humidity are lower than the recommended lower limit, the horn glue will cure more slowly, and if it is higher than the recommended upper limit, the construction time will be shortened.

  

  

  

Instructions

Remove dirt, dust, oil, frost, etc. on the surface of the substrate; place the plastic nozzle on the open bottle mouth and tighten it, and use a glue gun to paint from the hose and coat it on the surface of the substrate. In order to increase the curing speed and achieve complete curing faster, the product can be sprayed uniformly and appropriately with subsequent connection operations.

Precautions

After opening, it should be used up within days, otherwise it must be kept tightly sealed.
Avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water and consult a doctor if necessary; avoid contact with children; do not contaminate food, medicine or cosmetics. Foaming during curing, pay attention to check and clean the spilled glue.
The heavy workpiece to be bonded should be avoided to move before it is completely cured, and measures should be taken to fix it when it is necessary to move.
Recommended use conditions: temperature 15~35C, relative humidity 40%~80%; if the temperature and humidity are lower than the recommended lower limit, the horn glue will cure slowly, and the construction time will be shortened if the temperature and humidity are higher than the recommended upper limit.
