1. A two-component waterborne coating system comprising:
(A) a binder component comprising:
(A1) an aqueous dispersion of a hydroxy-functional polyacrylic polyol;(A2) optionally an aqueous dispersion of a non-functional polyurethane; and(A3) rubber particles having an average particle size no larger than 100 microns; and (B) a crosslinker component comprising a water-dispersible sulfonic acid-modified polyisocyanate; wherein a coating composition comprising component (A) and component (B) forms a cured polyurethane film exhibiting no greater than a 2 rating determined in accordance with GMW14445. |
