Wannate 8122 Modified MDI Used in Furniture,Toy and Automotive Industries

Application

WANNATE 8122 is a brown liquid at room temperature, consisting of a blend of polyol-modified diphenylmethane diisocyanate and polyphenylmethane polyisocyanate. It's particularly well-suited for producing viscoelastic foam in the furniture, toy, and automotive industries.

Typical Physical and Chemical Properties

Storage

Since WANNATE 8122 is a reactive chemical, it readily reacts with atmospheric moisture. This reaction forms insoluble ureas and carbon dioxide gas, which can lead to pressure buildup in closed containers and an increase in product viscosity. Therefore, containers must be completely dry and carefully sealed after being filled with nitrogen.

Store WANNATE 8122 containers indoors in a well-ventilated area at ambient temperatures (15-25°C), keeping them properly closed. Avoid storage below 10°C, as this may cause crystallization; the material must be protected from frost. If crystallization does occur, heat the material to 70-80°C to melt it. It's crucial to avoid localized overheating during this process. After melting, the product should be thoroughly agitated before use.

Shelf Life

WANNATE 8122 has a nine-month shelf life when stored under recommended conditions. Should the product's shelf life be exceeded, its functional properties may nonetheless remain unaffected, provided its primary physical and chemical characteristics conform to specifications.
