Storage

Solder paste should be stored between 3-8°C (37-46°F) to obtain the maximum refrigerated shelf life of six months.
Unopened solder paste stored at room temperature, 25°C (77°F) will have a one-month shelf life.
Syringes and cartridges should be stored vertically in the refrigerator with the dispensing tip down.

Allow 4-8 hours for the solder paste to reach an optimal operating temperature of 20-25°C (68-77°F).
Keep the solder paste container sealed while warming the solder paste to operating temperature.
