Polyvinyl chloride is the most common polymer for organosols Sec ond to PVC are the acrylics Polymer particles of colloidal size required for microgel formation can be formed by standard emulsion polymerization techniques. Effect of the solvent on film formation and the coating is important. Judicious choice of solvent must include : Thermodynamic stability of the sol, coalescence and evaporation during baking, and viscosity dictated by applications requirements.
