Packaging Drums,IBCs,tank containers and tank wagons
Storage Recommended storage temperature:+10 to +30ºC, storage stability(ex works): 6 months if stored in moisture-tight drums

Desmodur ® 44V20L may undergo partial crystallization at temperatures below 00C.The product can ,however, be brought back into the liquid state

by heating the entire contents of the drum for short time to a maximum of 700C, although this may lead to an increase in the solids content.Drums

- including empty ones-should always be kept tightly sealed. The product should never be allowed to come into contact with water,which reacts

with Desmodur ® 44V20L to form polyureas and carbon dioxide. Contact with water in any form (damp drums, solvents containing water, moist

air)must be prevented not only during storage, but also when removing material from drum and during processing. Failure to do so may lead to a dangerous build-up of pressure in tanks and drums due to the generation of carbon dioxide. In addition, polyureas forming in Desmodur ® 44V20L can cause solids to separate out, leading to blockages in the filters, pumps and pipelines of the processing equipment and resulting in production problems
