Modified MDI Huntsman 2020

Overview

Huntsman 2020 (Suprasec 2020) is a uretonimine-modified pure MDI that is liquid at room temperature. The modification prevents crystallization while keeping the reactivity of pure MDI, and the product has a low viscosity.

Also known as

Suprasec 2020; Uretonimine-modified MDI; Liquid MDI
