2. Typical physical and chemical properties

*These values provide general information and are not part of the product specification.

3. Package

200 liter iron drums, 225± 1kg/drum

4. Storage

Since WANNATE 8023 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 of the product. Containers must therefore be

absolutely dry and carefully sealed after congested with nitrogen.

Containers of WANNATE 8023 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 to heat over at local

part and should then be thoroughly agitated before use.

5. Shelf Life

Under recommended storage conditions, the shelf life of WANNATE 8023 is six 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.
