Yellow powder with little odor, no poison. The density is 1.03. It is not stability, it can be reduced content and then become to soluble sulfur. Insoluble in CS2 and water. Store a well ventilated area Below 300C, avoiding exposure to sunlight . Do not store near products that can emit free amines and Other alkaline vapors.

It is metastable, so the temperature should be kept as low as possible during mixing. Between 100-130 significant reversion can take place to soluble sulfur. Insoluble sulfur reversion can take place if it is in direct contact with alkaline components. Due to the best dispersion, during mixing it seldom appear electrostatic charge accumulating, form agglomerates and affecting mixing effect.

The product should be stored in the dry and Cooling place with good ventilation and Should be avoid hot and sunshine.
