5. Storage
Since WANNATE ® 8798 is a reactive chemical, reaction with atmospheric moisture happens easily and leads to the formation of insoluble ureas and carbon dioxide gas, which can result in pressure build up in closed containers and viscosity increase o f the product. Containers must therefore be absolutely dry and carefully sealed after congested with nitrogen.
Containers of WANNATE ® 8798 should be kept properly closed and stored indoors at ambient temperatures (15-35 ℃) in a well ventilated area. Storage at low temperatures (below 10 ℃) may lead to some crystallization; this material must be protected from frost. If crystallization does occur, the material should be heated to 70-80℃ to melt it out, strictly prohibit to heat over at local part and should then be thoroughly agitated before use.
6. Shelf Life
Under recommended storage conditions, the shelf life of WANNATE ® 8798 is nine months. If the production is overdue, but it’s main physical and chemical properties in the guide line, may not effect on it’s using properties.
