Packing & Storage

Colloidal silica is packed in 25kg or 250kg plastic drums.

Store the colloidal silica at a temperature between 0 and 50, avoid exposure to the air, and insulate it from the sun.

Wash the empty drums as quickly as possible to avoid SiO₂ crystalline deposits.

If you want to remove the deposition from empty drums, use a 10-percent NaOH solution at 50~60
