Factors Affecting Shelf Life

Emballage et stockage

You help decide how long aluminum paste lasts. Good packaging keeps out air, water, and light. Most brands use metal cans or drums with tight lids. These containers keep the paste from drying out. If you forget to close the lid, air and water can get inside. This can make the paste hard or lumpy.

Always store aluminum paste in a cool, dry spot. The best temperature is between 15°C and 25°C. If it gets hotter than 40°C, the paste can go bad faster. Some special leafing grades can handle up to 45°C, but heat is still not good. Sunlight, rain, and damp air can make the paste spoil sooner. You should keep the paste away from these things.

Tip: Put your containers on shelves, not on the floor. This keeps them dry and safe from spills.

Handling and Manufacturer Practices

How you use aluminum paste is important. If you shake or drop the can, the paste can separate. If this happens, mix it well before using. If the can looks swollen, open it slowly to let out pressure. This keeps you safe and protects the paste.
