  • Organosol plastisol compositions
    Patent number: 8034860
    Abstract: Both the viscosity of a plastisol comprising a dispersed polymer, a plasticizer for the polymers and at least one liquid diluent, and exudation of liquids from articles formed from the plastisol are minimized when the difference between 1) the weighted average of the Hildebrand solubility parameter values of all liquid ingredients, including plasticizer, in the plastisol and 2) the Hildebrand solubility parameter of the dispersed polymer is ±0.6 to ±1. The plastisols of the present invention are suitable for fabrication into films and molded objects, and as coating materials for a variety of metallic and non-metallic substrates.
    Type: Grant
