Polyaspartic technology utilizes a partially blocked amine to react more slowly with the isocyanates and thus produce a modified polyurea.
Eventually, the advantages of using polyaspartic esters as the main component of the co-reactant for reaction with an aliphatic polyisocyanate in low to zero volatile organic compound (VOC) coatings were realized.
This allows formulators to create high solids coatings systems which are user-friendly with longer working times and still maintain a fast-cure.
[10] Traditional aliphatic polyurea formulations required high-pressure, temperature-controlled plural component spray systems to be applied due to fast initial reaction rates.
Aliphatic polyaspartics can be formulated with slower reaction rates to accommodate batch-mixing and application by roller-applied methods or spray-applied through conventional single components paint sprayers without the use of solvent.
