WANNATE® 8122 is a mixture of polyol-modified diphenylmethane diisocyanateand and polyphenylmethane polyisocyanate. It is a brown liquid at room temperature. It is used in the production of furniture, toy and automotive industries, especially suitable for viscoelastic foam.
210 liter iron drums, 240kg/drum
Since WANNATE® 8122 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® 8122 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.
Under recommended storage conditions, the shelf life of WANNATE® 8122 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
