Patent
CA 2605274
The invention relates to coating agents comprising at least one pigment and/or filler and at least one aqueous dispersion of a selected vinyl ester copolymer stabilised with emulsifiers, containing a mixture of at least one non-ionic emulsifier and at least one salt of a bis-ester of a sulphonated dicarboxylic acid with 4 to 8 carbon atoms as emulsifier. The coating agents formulated with said binders are characterised by a high abrasion resistance.
La présente invention concerne des agents de revêtement contenant au moins un pigment et/ou une charge, et au moins une dispersion aqueuse d'un copolymère d'ester de vinyle sélectionné, stabilisé par émulsifiant, qui contient un mélange d'au moins un émulsifiant non ionique en tant qu'agent de stabilisation, et au moins un sel d'un ester bis d'un acide dicarboxylique sulfoné contenant de 4 à 8 atomes de carbone. Les agents de revêtement formulés avec ces liants, se caractérisent par des résistances à l'abrasion élevées.
