Storage and usage methods

1. Avoid light exposure (0-5 ℃), with a validity period of 6 months from the date of production.

2. After refrigeration, it needs to be left for 2-3 hours to recover to room temperature, and thoroughly stirred for 15 minutes before printing.

3. The viscosity of the product has been adjusted, and it is not recommended to use diluents. If there are special requirements, it is recommended to use the matching diluent.
