Aqueous Dispersion of Zinc Compound Modified Polymers

摘要

An aqueous polymer dispersion contains zinc compound-modified polymer. The zinc compound-modified polymer is produced by the incorporation of zinc compound into the acrylic-modified alkyd by mixing at the temperatures of higher than 50° C. The resulting polymer is then dispersed in water by salt formation with a base. The aqueous dispersion of the present invention offers improved coating properties of early water-spot resistance, hardness, ink stain blocking and scrub resistance while demonstrating the viscosity stability.
