Abstract
A water-borne, urethane and acrylic modified alkyd dispersion, wherein the dispersion is substantially surfactant free and has less than 1 weight % volatile organic compounds (VOCs) is described. Additionally, a method for preparing a water-borne, substantially surfactant free, urethane and acrylic modified alkyd dispersion, with less than 1 weight % VOC, is described. In the method, an acrylic modified alkyd polymer is reacted with a basic compound in water to form an acrylic modified alkyd dispersion having a first viscosity and then a hydrophobic seed is added thereto to form a urethane and acrylic modified alkyd dispersion having a second viscosity, which is substantially less than the first viscosity.
