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.
