Notice of usage and storage:

1.  The used material should be collected and sealed up alone. Don’t mix with other untapped material.

2.  Before using the paste, it is essential to take out of from icebox or icehouse firstly and place it at about 25. Keep stir it slowly and fully till the composition of this paste is uniform.

3.    It should be guarantee that the room temperature and appliance temperature remains 26±2 during printing.

4.    Paste material placed on the screen should be moderate and added regularly when making screen-printing.

5.    Dilute the paste moderately to recover the printing performance.

6.    The storage temperature is recommended between 5 and 25. The shelf time is commonly 6 months.

7.    Please test for products suitability before mass production to avoid causing unnecessary losses.
