Presentation of an emulsion polymer composition having fast drying properties that provides floor polish coating materials having superior resistance to black heel marks, resistance to scuffing, resistance to abrasion, adhesion, and resistance to cleaning agents characteristics, and floor polish coatings obtained from this polymer emulsion. A film forming emulsion polymer composition comprising 60 wt% or greater of a first emulsion copolymer having a glass transition temperature within the range of from 10-100°C, and 40 wt% or less of a second emulsion copolymer having a glass transition temperature that is lower than that of the first emulsion copolymer and is within the range of from 0-50°C, wherein the second emulsion copolymer contains less than 10% by weight of nonionic hydrophilic units selected from the group consisting of hydroxy alkyl ester of alpha, beta unsaturated acid, vinyl alcohol, alkyl-phosphato-alkyl acrylates and methacrylates, alkyl-phosphono-alkyl acrylates and methacrylates, and alkyl amides of alpha, beta unsaturated acid.

Présentation d'une composition de polymère en émulsion à séchage rapide qui confère aux produits de revêtement des cires à plancher des caractéristiques supérieures de résistance aux marques de talons, aux rayures, à l'abrasion, ainsi qu'à l'action des agents de nettoyage, et revêtements de cire à plancher obtenus avec cette émulsion polymérique. Composition de polymère en émulsion constituée de 60 % en poids ou plus d'un premier copolymère en émulsion ayant une température de transition vitreuse comprise entre 10 et 100 degrés C et de 40 % en poids ou moins d'un deuxième copolymère en émulsion ayant une température de transition vitreuse inférieure à celle du premier copolymère en émulsion et comprise entre 0 et 50 degrés C, et dont le deuxième copolymère en émulsion contient moins de 10% en poids d'unités non ioniques hydrophiles choisies dans le groupe suivant : ester hydroxyalkylique d'acide alpha, bêta-insaturé, alcool vinylique, acrylates et méthacrylates d'alkylphosphatoalkyle, acrylates et méthacrylates d'alkylphosphonoalkyle , et alkylamides d'acide alpha, bêta-insaturé.
