F520 NH1520 Polyaspartic Resin High solid transparent liquid
There is a development of a new class of aliphatic polyurea polymer systems. These systems are based on the reaction of polyaspartic ester compounds (a type of secondary aliphatic amine with aliphatic polyisocyanate). Polyaspartic ester-based polyurea topcoats are non-yellowing and exhibit good outdoor weathering and long pot life. 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.
