Storage condition
1. Lined with plastic bags, outer woven bags or gunny bags. Store in a cool, dry and ventilated place, away from fire. Tightly sealed packing to prevent moisture. Storage temperature should not be too high.

2. Store in a cool, ventilated warehouse. Keep away from fire and heat. It should be stored separately from oxidizers and acids, and should not be mixed. Equipped with the corresponding variety and quantity of fire equipment. The storage area should be equipped with suitable materials to contain leaks.

stability
1. It is heated and dissolved in organic solvent and cooled into a jelly. Strong acids decompose into stearic acid and corresponding zinc salts. Under dry conditions with fire risk, spontaneous ignition point 900℃.

2. Avoid contact with oxidants and acids. Flammable in case of open fire and high heat. Insoluble in water, ethanol and ether, soluble in benzene. It will decompose when it encounters dilute acid.

Water is Insoluble
