2 The Polyurea Reaction CN R` NC + H 2 N NH R 2 * R NH N H R' N H N H n * Isocyanate Amine Polyurea Very fast reaction for spray application No catalysts are needed 2

3 Morphology of Polyurea Elastomers Hard segment Soft segment Isocyanate Amine based chain extender Polyetheramines Polyurea coatings are elastomers with hard and soft segments Chain extender and polyetheramine widely determine the material properties 3

4 Polyetheramines Aminated C3-based Polypropyleneglycols H H n NH N 2 n H 2 D series (functionalityca. 2) MW AHEW Influence hardness hardness elasticity T series (functionalityca. 3) MW AHEW Influence rigidity elasticity 4
