2 Content What is Polyurea? Why develop new molecules? JEFFAMINE amine and JEFFLINK diamine overview Some ideas Summary

3 What is Polyurea? POLYUREA O O OCN NCO R + Isocyanate Prepolymer H 2 N NH 2 R' Polyamine R N H N H Urea Linkage R' N H N H n

4 Typical formulation A side: Isocyanate component Prepolymer, (MDI, HDI, IPDI) 100% B side: Amine (Resin) component Polyether amine 40-75% Amine chain extender 15-50% Additives 0-10% System processing: Volume ratio: 1:1. Index Application temperature & pressure: ºC C & bar

5 Features and benefits of Polyurea Two component, 100% solids system, typically 1:1 volume mix Fast reactivity and cure without a catalyst Relatively moisture and temperature insensitive during application High abrasion resistance Excellent physical properties Good adhesion to variety of substrates Good low and high thermal stability

6 Typical uses Concrete protection Secondary containment Bridge decking Park decks Sewage installations Flat roofing Steel protection

7 Why develop new molecules? We are in the business of making molecules. Is there room for improvement? Adhesion Reactivity Wear and tear Processing Extending and opening new markets

12 PPG based polyether amines (secondary) Proprietary Huntsman catalyst technology allows high secondary amine formation with little primary or tertiary. Intrinsic reactivity drops roughly a factor of 20 for secondary compared to primary amines. Steric hindrance plays an additional role in slowing the reactivity. Cure speed (gel time) of a formulation is dependent on concentrations and inherent reactivity. Products are stable, there is no off-gassing of reversible blocking agents.

13 PPG based polyether amines (secondary) R NH O n O NH R JEFFAMINE SD-231 amine JEFFAMINE SD-401 amine JEFFAMINE SD-2001 amine Approximate mol weight, g/mol Approximate functionality Kinematic viscosity, 25 C, cst Equivalent weight, gram/eq Designed to be used in conjunction with, or to replace, aromatic or aliphatic chain extenders, or to partially replace existing primary polyether amines. Slow down reactivity Produce low viscosity prepolymers
