Abstract
Aqueous wax dispersions useful as surface modifiers for paints, inks and coatings. More particularly, aqueous particulate wax dispersions useful as surface modifiers to provide improved properties in primers, paints, inks and other coating formulations. The dispersions are stable, substantially homogenous, have a high solids concentration at low viscosities, and comply with the applicable FDA regulations for use in food packaging applications.
Claims15
An aqueous wax dispersion comprising:
- a) water;
- b) at least one particulate wax dispersed within the water, wherein the particulate wax comprises particles having an average particle size of from about 0.1 μm to about 6 μm, wherein substantially all of the wax particles have a particle size of about 20 μm or less, and wherein the particulate wax comprises from about 5% to about 45% by weight of the dispersion;
- and
- c) from greater than 0% to about 5% by weight of a dispersing agent based on the weight of the particulate wax;
- which dispersing agent coats the surfaces of at least some of the wax particles;
- and wherein the dispersion has a viscosity of about 100 cps or less at about 25° C. at a wax concentration of about 10% by weight of the dispersion, and a viscosity of about 200 cps or less at about 25° C. at a wax concentration of about 45% by weight of the dispersion, and wherein there is substantially no agglomeration of the wax particles,
- wherein the aqueous wax dispersion is prepared at a temperature or temperatures that are maintained below about 50° C.
