Abstract:
1. A composite dispersion comprising: a first seed dispersion comprising; a second internal phase comprising a second hydrophobic material; wherein said composite dispersion comprises more than 60 percent by the combined weight of the first internal phase and the second internal phase, and said composite dispersion has a viscosity of less than 10,000 cP measured by RV4 spindle at 20 rpm at greater than 60 weight percent total internal phase, and wherein said composite dispersion has a bimodal particle size distribution and a particle size ratio (P2/P1) in the range of 2 to 200, wherein the particle size ratio (P2/P1) of the bimodal distribution is defined to be the particle diameter at the maximum of the larger diameter particle population (P2) divided by the particle diameter at the maximum of the smaller diameter particle population (P1), wherein one or both of said first hydrophobic material and said second hydrophobic material comprises same or different alkyd, at least one of said alkyds comprising the reaction product of one or more polyhydroxyl alcohol and one or more polycarboxylic acids in the presence of drying oil.
