Abstract
This paper describes the development of a new class of polyurea polymer coating. Specifically, the use of polyaspartic ester compounds, which are secondary aliphatic diamines, in combination with aliphatic polyisocyanates to form aliphatic polyurea coatings are described in this paper. Polyaspartic ester-based polyurea topcoats are non-yellowing, exhibit good outdoor weathering and long potlife. The moderately fast reactivity, combined with the relatively low viscosity of the polyaspartic ester compounds allows for a broader range of applications in two-component coatings.
