DESMODUR® VP.PU 60RE70
DESMODUR VP.PU 60RE70 is a mixture of 4,4'-, 2,4'- and 2,2'-diphenylmethane diisocyanat with a relatively high content of 2,4'-isomers. It can be used in conjunction with polyols for the production of polyurethane products.

General Characterization
It can be used in combination with polyols for production of polyurethanes.
Storage Conditions
Storage stability (ex works): 6 months if stored in moisture-tight drums
Storage for long periods at temperatures below 20 °C or above 35 °C leads to a deterioration in quality.
At temperatures below 20 °C starts crystallisation, encouraging the formation of infusible dimers. This makes it impossible to completely melt the product, even if it has been stored for only three weeks.
Storage at temperatures above 35 °C also accelerates the formation of insoluble sediment (dimers).
Freshly crystallised DESMODUR VP.PU 60RE70 must be remelted . In doing so, it is important to ensure that the entire contents of the drum are melted and homogenised.
The drum should then be kept sealed at the standard storage temperature
(20 to 35 °C).
