Storage
Storage in original sealed Covestro containers.Recommended storage temperature (°C): 20 - 40Protect from moisture, heat and foreign material.Covestro represents that, for a period of 6 months following the day of shipment as stated in the respective delivery documents, the product will meet the values set forth in section "specification" above provided that the product is stored in full compliance with the storage conditions and is otherwise handled appropriately. The lapse of this period does not necessarily mean that the product no longer meets specifications. However, prior to using said product, Covestro recommends to test such a product if it still meets the specifications. Covestro does not make any representation regarding the product after the period and Covestro shall not be responsible or liable in any way for the product failing to meet specifications after the period.Partially used containers should be tightly resealed due to the hygroscopic nature of the product.Recommended temperature for processing (°C): 20 - 25.
Processing
The viscosity of the Desmodur® VP.PU 10WB94 increases with the storage time. This viscosity increase does not limit the processability of the product according to our experience.The Desmodur® VP.PU 10WB94 can partly cristallize at a temperature below 15 °C. The product can be heated for a short period of time at a temperature under 70 °C in order to make it liquid again. Under such conditions, the solid content of the product can become higher.
