PPR F520
Polyaspartic Polyurea Resin F520
PPR F520 is an aminofunctional co-reactant for polyisocyanates useful for the formulation of high-solids, two-component polyurethane topcoats and solvent-free coatings. PPR F520 can be reacted with -NCO functional HDI trimmer resulting in a longer gelling time and excellent yellowing resistance.
