A water-based coating composition that is particularly suited as a floor coating. The composition is an aqueous two-part or two-component polyurethane system, having a water-dispersible polyisocyanate component and a hard cyclic diol component. The composition may be applied over a primer coating. The composition can be applied as a fairly thin coating, e.g., less than 127 micrometers (5 mils) thick, and provides a suitable coating with one coat. The composition, when coated onto a surface such as a floor, can be cured under ambient conditions. The resulting coating provides a durable coating with high gloss.

La présente invention a pour objet une formule aqueuse de revêtement qui est particulièrement adaptée au revêtement d'un sol. La formule est un système polyuréthane aqueux en deux parties ou bicomposant, qui comporte un composant polyisocyanate hydrodispersible et un composant diol cyclique dur. La formule peut être appliquée sur une sous-couche. La formule peut être appliquée sous forme d'un revêtement relativement fin, par exemple d'épaisseur inférieure à 127 micromètres (5 mils), et permet d'obtenir un revêtement adapté en une seule couche. La formule, lorsqu'elle est appliquée sur une surface telle qu'un sol, peut être durcie dans des conditions ambiantes. Le revêtement résultant présente une durée de vie et une brillance importantes.
