  • Method for optimizing a hegman rating of a diluted emulsion, a diluted emulsion produced thereby, and a coating made
    Patent number: 10851213
    Abstract: A method for optimizing a Hegman rating of a diluted emulsion including adjusting the shear work in the dilution mixer, wherein the adjusting the shear work may comprise raising or lowering the shear work; adjusting the temperature of the concentrated and/or diluted emulsion; if not earlier added, adding a basic aqueous solution and/or dispersing agent; adding one or more other additives; and/or adjusting the amount of any additive, basic solution or surfactant solution is provided. Also provided are diluted emulsions produced thereby and coatings made from the diluted emulsions.
