4,4′ Diphenylmethane Diisocyanate

Lupranate LP27 Isocyanate is a special modified pure 4,4′-diphenylmethane diisocyanate that is a clear liquid at 27°C. Unlike pure 4,4′-MDI, Lupranate LP27 Isocyanate has enhanced storage stability as a liquid at moderate temperatures. With a functionality of 2.01 and very high 4,4′-MDI content, Lupranate LP27 can be used in place of pure 4,4′-MDI in many applications, including the preparation of prepolymers, elastomers, sealants and adhesives.
