instructions

Transportation: This product is transported in ice cubes at -0 ℃.

Unsealing: Remove the syringe from the ice cube and immediately place it in a refrigerator below 0 ℃.

Storage: stored at -40 ℃ environment, can be preserved for 6 months- Stored at 20 ℃, it can be preserved for 3 months. Under the required storage conditions, the performance of the product can be guaranteed. Inappropriate storage conditions can cause a deterioration in the dispensing performance and usability of the product after curing (the lower the storage temperature, the longer the shelf life).

Warm up: This product needs to be warmed up to room temperature before use. After removing from the refrigerator, place the syringe vertically and do not open the container until the product has returned to room temperature. Any water vapor that condenses on the container during the warming process must be removed before opening the container.

Attention: The glue that has been warmed up must be immediately placed on the dispensing equipment for use. If it is necessary to transfer the product to the later dispensing machine, be careful and avoid introducing impurities or air during the transfer process.

The thawed glue should be used up within 24 hours.

The number of times the product needs to be warmed and thawed should not exceed 3 times.
