PACKAGING:
Packed in a metal pail lining with a polyethylene plastic pouch, and lashed with a rope, the vessels must be sealed up. The net weight per pail is 100kg, 50kg, 40kg or 25kg. On the package it should be marked clearly “Dampproof”.
Store in an aeration-drying storehouse, don’t place in the open air. Preserving it from damp air. It should not be stored or transported with inorganic acid, tinder. It should be kept away from the sunshine and rain. During loading and unloading it should be moved with great care, avoiding breakage.
In case of fire, it can be put out by water, sandy loam and all types of fire extinguishers.

Usage:
Used for bottom paint in ship manufacture, coatings, dyestuff, metallurgy, chemicals and pharmaceuticals.
