Modified MDI BASF Lupranate MM103C

Overview

Lupranate MM103C is a modified MDI from BASF: a carbodiimide-modified 4,4′-diphenylmethane diisocyanate that stays liquid at room temperature. It is easier to store and handle than solid pure MDI while keeping a high NCO content and low viscosity.

Also known as

Modified MDI; Liquid MDI; Carbodiimide-modified MDI

CAS number

101-68-8 (4,4′-MDI, main component)
