Polymeric Isocyanate Desmodur About

General Properties and Applications

Desmodur 44V20 is a liquid, dark brown polymeric isocyanate based on diphenylmethane-4.4-diisocyanate (MDI) with isomers and homologues of higher functionality. It is used in conjunction with polyols to produce polyurethane.

Specification

Property	Value	Unit of measurement	Method
NCO content	30.5-32.5	% by wt.	MDI-01-01
Viscosity 25 C*)	160-240	mPs	MDI-01-02
Acidity	max.200	mg/kg	MDI-01-03
*) Lengthy storage can lead to an increase in the viscosity of Desmodur 44V20 L, although in our experience this has no adverse effect on the processing properties of the product.
