储存条件
Recommended storage temperature (°C): 20 - 40
The product must be stored in sealed, moisture-tight containers. Partially used containers should be tightly resealed due to the hygroscopic nature of the product.
Lengthy storage leads to an increase in the viscosity of Desmodur® VP.PU 3230, although in our experience this has no adverse effect on the processing.
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.
