features/applications
desmodur® n3900suitable for preparing high solids systems for automotive refinishing, transportation coatings and plastic coatings.

compatibility
desmodur® n3900can be used with the followingdesmodur®anddesmophen®mixed use of series products:desmodur® n75, n100、n3200, n3300,n3390 ,n3400、 n3600andz4470; most polyester typedesmophen®series products, such as:desmophen® 670,680,vpls2089andvpls2107 and acrylics. desmodur® n3900withdesmophen® 650 and 651incompatible.

solubility/dilution
desmodur® n3900compatible with the following solvents: ethyl acetate, butyl acetate, propylene glycol methyl ether acetate, acetone, methyl isobutyl ketone, cyclic hexanone, toluene, xylene, naphtha® 100 menthal spirit and its mixed solvent. aliphatic hydrocarbon solvents should not be used. desmodur® n3900dilution to solid content below40%. solvents with low binder content should not be stored for long periods of time, as this can lead to cloudiness and sedimentation.
