Product description
Mondur CD is a carbodiimide modified 4,4’-diphenylmethane-diisocyanate (MDI) which is liquid at room temperature.
Applications
Mondur CD is used in the production of elastomers (solid and microcellular) and in the preparation of prepolymers for elastomer, sealant, adhesive and coating applications. As with any product, use of Mondur CD in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

Storage
Mondur CD must be stored in tightly sealed containers and protected from moisture. Like all isocyanates, Mondur CD will react with water to form ureas and carbon dioxide. The generation of carbon dioxide in sealed containers can lead to a dangerous pressure build-up resulting in deformation and/or rupture of the container. Once a container has been opened, care should be taken to exclude moisture. This can be accomplished by padding the material with dry nitrogen and tightly sealing the container after each use.
To maintain the quality of the product, Mondur CD should be stored between 20 and 30°C (68 and 86°F) and protected against moisture. Storage for long periods at temperatures in excess of 30°C (86°F) leads to deterioration in quality, with the product becoming increasingly turbid due to the formation of dimer. Storage at too low a temperature, even for short periods of time, can result in the formation of solid MDI crystals, which occurs at approximately 15°C (59°F). Prolonged storage of frozen or partially frozen Mondur CD will result in undesirable dimerization that could make the product unusable. During the winter months, appropriate precautions must be taken during shipment and storage of this product.
Warning: Prolonged exposure of Mondur CD to temperatures in excess of 70°C (158°F) may cause dangerous pressure build-up, resulting in the deformation and/or rupture of sealed containers. To prevent excessive local over-heating, avoid the use of electrical heat tape and open flames when heating this product. Pressure curves for Mondur CD at various temperatures are shown below to provide the customer with additional information.
Caution: When producing prepolymers, Mondur CD should not be used in combination with amino-polyols, or polyols containing high residuals of basic materials. As with any product, the use of Mondur CD should be evaluated for a given application by the customer to determine suitability.
Storage time
The shelf life is six months after receipt of material by customer, when stored in sealed original containers under conditions stated above.
