摘要:
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.
摘要:
The invention relates to a coating composition comprising an autoxidizable alkyd-based resin and a drier composition, the drier composition comprising: a) an iron-ligand complex comprising iron and at least one bispidine ligand; and b) a vanadium compound; wherein the amount of the vanadium compound is such that the coating composition comprises vanadium in a concentration in the range of from 0.01 wt % to 1.0 wt %, based on the solid weight of alkyd-based resin and wherein the amount of iron-ligand complex is such that the coating composition comprises iron in a concentration in the range of from 0.5·10−4 wt % to 5·10−3 wt %, based on the solid weight of alkyd-based resin.
