ISONATE™ 143L Modified MDI is a polycarbodiimide-modified diphenylmethane
diisocyanate. Liquid at room temperature, this product has a low viscosity and good storage
stability down to 75°F (24°C). The polycarbodiimide adduct offers extra flexibility because
adduct formation is reversible (dissociation generates an additional isocyanate function).
The carbodiimide linkage aids the stabilization of the polymer against hydrolytic
degradation.
