  • RESIN EMULSION COMPOSITION, AND PROCESS OF OBTAINING SAME
    Publication number: 20170029573
    Abstract: The present invention relates to aqueous resin emulsions containing at least a non-ionic surfactant of general formula R1—(A1O)n—(A2O)x—(A3O)y—R2, obtained by the phase inversion emulsification process. In particular, the invention relates to aqueous resin emulsions commonly used in solvent-based paints, such as, for example, alkyd resins. Said emulsions are stabilized by non-ionic and anionic surfactant compositions which promote the inversion of the water-oil to oil-water phases in the presence of low water content, enabling water-oil type emulsions to be obtained with high productivity and high solids content, even in low shear conditions.
