Storage:
Since WANNATE 6112 is a reactive chemical, reaction with atmospheric moisture happens easily and leads to the formation of insoluble urea and carbon dioxide gas, which can result in pressure build-up in closed containers and viscosity increase of the product. Containers must therefore be absolutely dry and carefully sealed after congested with nitrogen.

Containers of WANNATE 6112 should be kept properly closed and stored indoors at ambient temperatures (15-25℃) in a well-ventilated area. Storage at low temperatures (below 10℃) may lead to some crystallization; This material must, therefore, be protected from frost. If crystallization does occur, the material should be heated to 70-80℃ to melt it out, strictly prohibit over heating at local part and should then be thoroughly agitated before use.

Prolonged storage over 50°C is prohibited in order to avoid formation of insoluble solid and viscosity increase of the product. If the production is overdue but its main physical and chemical properties are in the guide line, the using properties may not be affected.
Shelf Life
Under recommended storage conditions, the shelf life of WANNATE 6112 is six months from the production date.
Safety
WANNATE 6112 is of low toxicity by inhalation and skin absorptio
