Product Description

General Properties and Applications Desmodur ® 44V20L is a dark-brown, liquid blend of  diphenylmethane-4,4'-diisocyanate (MDI) with isomer and homologues of
higher functionality. It is used in conjunction with polyols to produce rigid polyurethanes foam.

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
