Characterization
Monomeric diphenylmethane diisocyanate with high 2,4'-isomer content and stabilized against discoloration during storage.

Formulation of prepolymers for use in one- and two-component polyurethane coatings and adhesives and in related applications. Desmodur® 2460 M is

an isomeric mixture of monomeric diphenylmethane diisocyanate that is liquid at temperatures above 20 °C. Storage and handling are greatly simplified

compared to 4,4' isomer that is solid at room temperature (Desmodur® 44 M, Desmodur® 44 MC)

Form supplied

Colorless to yellowish liquid of low viscosity at temperatures above 20 °C that crystallizes at lower temperatures

Processing
It must be ensured that the containers - including those that are empty - are kept sealed. Above all, contact with water must be prevented as it reacts with Desmodur® 2460 M to form polyureas and carbon dioxide. During storage,sample withdrawal,transfer and processing of Desmodur® 2460 M,the ingress of water in any form (damp containers, aqueous solvents, moist air) must be prevented as otherwise the formation of carbon dioxide
may cause a dangerous increase in pressure in the tanks and containers. Furthermore, the formation of polyureas in Desmodur® 2460 M may cause turbidity and possibly
solid deposits which may then block filters, pumps and pipelines.

Storage
Storage in original sealed Covestro container.

- Recommended storage temperature: 20 - 40 °C.

- Protect from moisture, heat and foreign material.

General information: The product is sensitive to moisture and should therefore be stored in its sealed original containers. Prolonged storage at temperatures above 45 °C results in a deterioration in quality as the product becomes increasingly turbid owing to the formation of a sediment (dimers) that is not readily soluble. Storage at too low a temperature results in crystallization which starts at around 15 °C.The storage of the crystallized product above 5 °C must be avoided as this promotes the formation of non-meltable dimers.As a result,the product can no longer be fully melted after around 3 weeks. To prevent crystallization, it must be ensured that the product does not cool to below 20°C. Upon receipt, samples of the product should be tested for crystallization. If crystallization has occurred during transportation or storage, the product must be remelted immediately. On no account should the temperature during melting (material temperature) exceed 70 °C nor should the time needed to reliquefy the product be exceeded as this will greatly promote the formation of non-meltable dimers. It should be ensured that the entire content of the container is remelted and homogenized. The container must then be closed immediately and its content cooled to and kept at the standard storage temperature (20 - 25 °C). If the product is in a partially crystallized state for a brief period, there will be no significant effect on the product quality. Only the storage stability may be reduced slightly, i.e. remelted product should be used as soon as possible.

Storage time
Covestro represents that, for a period of six months following the day of shipment as stated in the respective transport documents, the product will meet the specifications or values set forth in section "specifications or characteristic data" above,what ever is applicable, provided that the product is stored in full compliance with the storage conditions set forth in and referenced under section "storage" above and is otherwise handled appropriately.The lapse of the six months period does not necessarily mean that the product no longer meets specifications or the set values. However, prior to using said product, Covestro recommends to test such a product if it still meets the
specifications or the set values. Covestro does not make any representation regarding the product after the lapse of the six months period and Covestro shall not be responsible or liable in any way for the product failing to meet specifications or the set values after the lapse of the six months period.
