Packaging & Storage:

S76L is packaged in aluminum-foil-laminated vacuum bags inside plastic drums or cartons, with a net weight of 20.00 kg ± 0.02 kg per drum. Alternative packaging such as ton bags or cartons can be arranged by agreement. When sealed under vacuum and stored in a cool, dry place, the shelf life is one year.

Handling Notes:

Avoid impact and inversion during transport
Store in a clean, ambient, cool and dry environment
Protect from direct sunlight, heat, and rain during transport
Use immediately after opening; if not used immediately, reseal to prevent moisture absorption
