Desmodur ® T 65 NStorage- Storage in original sealed Bayer MaterialScience container.- Recommended storage temperature: 18 - 40 °C.- Protect from moisture, heat and foreign material.Storage timeGeneral information: The product is sensitive to moisture and heat. It shouldbe protected against contact with atmospheric moisture. Prolonged storageat elevated temperatures may result in discoloration or in the formation ofinsoluble deposits. The product crystallizes at temperatures below 5 °C.However, careful heating will reliquefy the product without any detrimentaleffect on its quality. The reliquified product must be homogenized ascrystallization causes a shift in the isomer ratio between the crystalline andthe still liquid phases. Opened containers must be resealed after removingproduct. If stored for long periods, the product should be overlaid with nitrogen.The product reacts with water to release carbon dioxide. During storage,transfer and handling of the product, contact with water in any form (dampcontainers, solvents containing water, moist air) must be prevented as thegeneration of carbon dioxide may result in a dangerous increase in pressure.The polyureas which are formed at the same time may result in turbidity. Theymay also cause blockages and breakdowns in filters, pumps and pipes.Bayer MaterialScience represents that, for a period of twelve months followingthe day of shipment as stated in the respective transport documents, theproduct will meet the specifications or values set forth in section "specificationsor characteristic data" above, what ever is applicable, provided that theproduct is stored in full compliance with the storage conditions set forthin and referenced under section "storage" above and is otherwise handledappropriately.The lapse of the twelve months period does not necessarily mean that theproduct no longer meets specifications or the set values. However, prior tousing said product, Bayer MaterialScience recommends to test such a productif it still meets the specifications or the set values. Bayer MaterialScience doesnot make any representation regarding the product after the lapse of the twelvemonths period and Bayer MaterialScience shall not be responsible or liable inany way for the product failing to meet specifications or the set values afterthe lapse of the twelve months period.page 2 of 3Edition 2012-03-19 Desmodur ®Replaces edition dated 2011-06-01Product Datasheet
